Judge Interview Playbook

A judge interview is a short conversation at your pit. Judges listen for evidence that you did the work, learned from it, and did it together. This guide shows what they listen for and how to get every student ready to tell their part.

Spartan practice: Recall your own work, decisions, failures, learning, and collaboration. These questions and examples are prompts, not a speech to memorize or a required question order. Use real evidence, acknowledge uncertainty, and let the students involved explain their contributions. See the current interview rubric guide and student-centered policy guidance.

// Section 01
What the Interview Actually Is
A short conversation in your pit. Judges listen for evidence that you did the work, learned from it, and did it together.

Points for Delivery
Judges score what you say, not how polished it sounds.
📋 IF YOU READ NOTHING ELSE, READ THIS
  1. Know the six criteria and the kind of question that goes with each one (Section 2).
  2. Write your Season Summary and be ready to tell the story behind every highlight on it. Judges often open with one (Section 3).
  3. Know who did what, and let the person who did it explain it (Section 4).
  4. Bring specifics: a named part, a number, a source, a specific moment (Section 5).
  5. Use the criterion question bank, including teamwork questions (Section 6). Three practice rounds are a Spartan suggestion, not a scoring requirement.
🏆
One sentence: judges want to hear that you did the work, that you learned from it, and that you did it together, told with real specifics.

How a GRSF Interview Works

OFFICIAL Summarized from GRSF: Judging Team Interviews. The linked article controls.

What Judges Are Told

⚖️
“Score the content of the answer, never the delivery.” Nervousness, pauses, accent, comfort level and accommodations aren’t scored.
“Preparation is what we asked for.” Practicing is expected. If an answer sounds rehearsed, judges ask a follow-up and score what they hear.
“Judges are not investigators.” They aren’t looking for problems. Thin evidence just means a lower score on that criterion.
Not held against you: credited outside ideas, official VEX Hero Bots and code starting points (including unchanged official starting points), and practiced answers. Judges still need relevant evidence for each row.
Packet alignment · October 23, 2026: This playbook incorporates the Spartan Design first-time judges companion. That packet is local guidance, not an official GRSF publication; its wording and timing add no scoring requirements. Use the official rubric for event scores.

A 10-Minute Classroom Practice Round

This is the packet’s local planning example, not a GRSF time limit. At an event, follow the Judge Advisor’s schedule and participation arrangements.

  1. 1 minute — Welcome: invite the team to tell its learning story. Different students can answer different questions; notebooks may help.
  2. 4 minutes — Learning: explain your work, trace its development, and describe how you tested it.
  3. 4 minutes — Collaboration: describe learning together, shared decisions, and outside ideas.
  4. 1 minute — Coverage and close: ask about any missing area, then invite anything else the team wants to share. Closing evidence still counts.

With two practice judges, switch who asks and who takes notes halfway through; both listen throughout. Allow a further 2–3 minutes for private scoring and comparison.

Fair Opportunity Before Scoring

Classroom practice and event records are different. Follow your teacher’s recording and submission directions for classroom mocks. Completed event judging notes and rubrics stay with judges and the Judge Advisor and are destroyed at event close; judging photos are deleted. Do not retain real event interview quotes, recordings, or scores for future calibration. Use fictional cases for judge training.

It Is a Conversation, Not a Presentation

Prepare to talk about your work and respond to follow-ups. A judge is a curious engineer asking questions, not an audience. Answer what they actually ask.

❌ Presentation Mode
  • A speech from the top, regardless of the question
  • One person explains parts they didn’t work on
  • Only the finished robot, never the journey
  • Robot features only, no teamwork stories
✅ Conversation Mode
  • Listens, then answers the question asked
  • The student who did the work explains it
  • Teammates add to and build on each other’s answers
  • Includes what failed, what you learned, and who you learned it from

How the Interview Feeds Awards

Interview scores help judges sort teams at the start of deliberations, but an interview alone doesn’t win an award. Judges also use the Engineering Notebook and what they see at the event. A team can win only one Judged Award per event.

OFFICIAL Summarized from GRSF: Award Descriptions. Check the full criteria and the Award Requirements Quick Reference before each event.

Excellence — meets the Design criteria, is a strong candidate for other Judged Awards, shows positive conduct, and finishes in the top 40% of Qualification, Robot Skills and Autonomous Coding Skills rankings (score above zero).
Design — an organized, student-driven design process shown through the notebook and the interview. Requires a fully developed notebook that ranks among the strongest at the event.
Innovate — a novel design element or strategy in use at the event, documented from concept through implementation, showing independent inquiry. The team must also meet all Design criteria.
Think — well-organized, documented code, a clearly explained programming strategy, organized version management, and an Autonomous Coding Skills score above zero.
Build — a durable, reliable, safe robot built with attention to detail. Students explain the design and construction process.
Amaze — a highly capable, consistent robot that contributes to match success, performs well in Driving and Autonomous Coding Skills, and is explained by its students.
Create — a creative, ambitious engineering solution to this season’s game, explained by its students.
Judges — recognizes something that doesn’t fit another award, such as perseverance, growth or community impact.

Talking About an Innovation

If you think part of your robot or strategy is truly novel, make it easy for judges to see. Put it on your Season Summary as a highlight, point to the notebook entries that show it developing, and be ready to talk about it in the interview.

ℹ️
Earlier seasons used a written Innovate Award submission form limited to one aspect. GRSF’s current award descriptions don’t list a form, so follow your event’s instructions if it asks for one.
// Section 02
The 6 Criteria Judges Listen For
Two sections, three criteria each. Every question a judge asks is looking for evidence on one of these.
📌 Quick Take Explain Your Learning (6 pts) and How You Worked With Others (6 pts). Each criterion is scored Heard, with Specifics (2), Heard (1) or Not Yet Heard (0). A solid interview where everything is “Heard” scores 6 of 12. Specifics are what move a criterion to 2.

OFFICIAL Criteria and sample questions from the GRSF Team Interview Rubric v2.0. The “Recall” notes are Spartan preparation tips. See also our rubric guide.

What Counts as “Specifics”

The listen-fors are examples, not a checklist. A relevant reason, sequence of attempts, precise observation, or shared learning moment can provide concrete detail. No required number of redesigns, trials, named students, or equal speaking-time quota applies.

🔩 A named part 📏 A number (count, time, measurement) 🔗 A source 🕑 A specific moment

Section A — Explain Your Learning

Criterion 1
Students explain their own work

Let the student who knows a part explain how it works or why the team chose it. Alternatives can help explain the choice; no one must explain everything, and a list of alternatives is not required.

“Pick a part of your robot or code, walk me through how it works and why you built it that way.”
Recall: your mechanism or code, the alternative you rejected and why, and the math or science that explains the choice (gear ratio, torque, sensor behavior) if it’s part of the why.
Criterion 2
Students trace how they got there

Tell your attempts in order: something that did not work, what you did next, and a moment (a test, a mistake, a conversation) that changed your thinking.

“Tell me about a problem that took more than one try. What did you try?”
“What’s something you built or coded that you ended up throwing away?”
Recall: the problem you defined, the ideas you brainstormed, how you picked one, and each version since. Failures are great answers here.
Criterion 3
Students show how they know it works

Describe what you tested, a concrete result, and how it informed your thinking. Counts, times, and measurements can help; a precise observation also counts. There is no required trial count in this interview rubric.

“How do you know that works?”
“What can you do now that you couldn’t at the start of the season?”
Recall: one test with a concrete before/after observation or measurement, and what you learned from it. Use your actual results; numbers are not required.

Section B — How You Worked With Others

Criterion 4
Students learned from and with each other

One student taught another a skill they could use, students add to each other’s answers, and you can share a moment you figured something out together.

“What’s something you taught a teammate this season?”
Recall: a usable skill shared or a moment of understanding together. Building on a teammate’s answer is evidence too; a separate teaching story from every student is not required.
Criterion 5
Decisions were made together

Explain how students reached a shared decision. Resolving different ideas is one possible example; a disagreement is not required.

“Who worked on what?”
“Tell me about a time your team disagreed about what to do. How did you decide?”
Recall: a shared choice, the options or priorities you considered, and how you chose together. A test, discussion, decision matrix, vote, or compromise may help tell that story.
Criterion 6
Outside ideas were made their own

Explain how your team used an outside idea. Credit, adaptation, testing, and understanding are examples of evidence, not four required boxes. An official VEX starting point may be unchanged; using it does not automatically earn points or make this row N/A.

“Where did the idea for that come from? What did you change about it?”
“Which other team(s) have you learned something from?”
Recall: the sources on your Credit Summary, such as a team, a video, a template or a library, and what each one became on your robot. Crediting a source never counts against you.
⚠️
The most common gap: teams practice robot explanations all season and never practice teamwork stories. Section B is half the score. Prepare real details for criteria 4, 5, and 6. One story can support several rows when its evidence is relevant to each.

Where Do EDP, STEM and Strategy Fit?

They aren’t separate scoring categories. They’re the evidence inside your answers:

// Section 03
Start From Your Season Summary
Judges read it before they reach your pit, then ask you to walk them through it. Prepare the stories behind it.
📌 Quick Take The Season Summary is a one-page overview submitted with your notebook. Judges read it first, pick a highlight and say “walk me through this.” Every highlight on it should have students who can tell its story with specifics. The summaries aren’t scored, but they shape the questions.

OFFICIAL Rules from GRSF: Season, Code, and Credit Summaries for Judging. How to write them: Season, Code & Credit Summaries guide.

The Three Summaries and the Interview

Season Summary · required if you submit a notebook
What you learned, skills you built, what the robot can do

Judges usually choose an interview opener from it. Prepare: for each highlight, know which students lived it, what happened in order, one number or moment, and which notebook entry shows it.

Code Summary · required if you use code
What your code does, in what order, and how it chooses paths

Prepare: the students who wrote the code can explain it in plain language, including a choice that changed after testing (criteria 1–3).

Credit Summary · outside sources you use
Videos, teams, websites, templates, libraries

Prepare: for each source, what you changed, how you tested it, and why it works. That’s criterion 6. Crediting never counts against you.

✍️
Students write all three. No adult and no generative AI tool may write the summaries. For a paper notebook, hand them in as loose pages at the front. For a digital notebook, include them as labeled first pages or a listed appendix in the single file.

Drill: Highlight Walk-Through

  1. One person plays the judge, picks any highlight from your Season Summary and says “walk me through this.”
  2. The students involved tell the story: what you tried, what failed, what changed, how you know it works.
  3. The “judge” asks one follow-up: “who else worked on that?”, “what did you try before?” or “show me in the notebook.”
  4. Repeat until every highlight has been told by the people who did it.
✅
If a highlight is hard to talk about, it either isn’t really your team’s story or the notebook doesn’t support it. Fix the summary, not the speech.

No Season Summary? You still get the same interview, scored on the same rubric. Judges will just start somewhere else, usually your robot.

// Section 04
Who Did What — Ownership and Building on Each Other
Let the person who did the work explain it, and let teammates add to it. Both are evidence.
📌 Quick Take The student who did a piece of work explains it. Teammates add to and build on each other’s answers, and GRSF lists that as a sign of a real conversation. Use “I” for your part and “we” for what you decided or figured out together. There’s no equal-time quota.

“I” and “We” Are Both Evidence

Say “I” for

The part you built, coded, tested or wrote. “I rebuilt the intake after the jam tests.” This is criterion 1 evidence.

Say “we” + names for

Decisions, disagreements and things you learned from each other. “Ana and I disagreed on the drive, so we ran both.” That’s criteria 4 and 5.

The Hand-Off

🏆
When a question is about a teammate’s work, give a sentence of context and pass it by name: “We chose a four-bar to keep the claw level — [Name] ran the tests that decided it.”
  1. Work out what was asked and who actually worked on it
  2. Answer what you know, or invite the teammate who did the work
  3. Pass to them by name
  4. Teammates can add detail afterward (“and the reason we didn’t use chain was…”). That’s building on each other, not interrupting
👥
Invite contributions from the students who did the work. A pause, nervousness or uneven speaking time doesn’t by itself show a lack of understanding. Judges are told to allow silence and to invite quieter students in.

Ownership Planner

Write down who actually lived each story, so the right people are ready to tell it. These are starting points, not a speaking order. Saved in this browser only.

Adults at the Interview

Coaches, mentors and parents can be present, but students answer every question. If an adult answers, judges will politely redirect. It isn’t held against the team. Coaches: stand back, and let pauses happen.

When You Don’t Know the Answer

Say what you know, what you’re unsure about, and who or which record could clarify it. Honest uncertainty is better than a guess.

// Section 05
Evidence and Specifics
Specifics move a criterion from Heard (1) to Heard with Specifics (2). The examples below are illustrative. Use your own.
📌 Quick Take A specific answer names a part, gives a number, credits a source or describes a moment. “We changed the gear ratio from 1:5 to 1:7 because the arm sagged under cup weight” is specific. “We tried different gear ratios” isn’t.

Using the Notebook and Robot

You may open your Engineering Notebook during the interview. Judges treat that as an engineer checking documentation. Use it when it helps you recall or show something. You don’t need to cite a page for every answer, and the criteria don’t depend on the notebook being there.

Vague vs Specific — Explain Your Learning

HEARD · CRITERION 1“We have a four-bar lift on our robot.”
WITH SPECIFICS“I picked a four-bar because it keeps the claw level. A single arm was simpler, but the claw tilted as it rose, and a wrist would have needed a motor we didn’t have.”
HEARD · CRITERION 3“Our autonomous is really consistent now.”
WITH SPECIFICS“It was missing 4 of 10 runs. The log showed the IMU drifting because it hadn’t finished calibrating. We added a wait, and it’s hit 9 of 10 since.”

Vague vs Specific — Working With Others

HEARD · CRITERION 4“We all helped each other learn.”
WITH SPECIFICS“Maya showed me how to put the IMU heading on the brain screen. That’s how I found the drift in our skills auton.”
HEARD · CRITERION 5“We decided as a team.”
WITH SPECIFICS“Two of us wanted a six-motor drive and two wanted a lift motor instead. We timed both on the same route. The four-motor drive was only 0.4 seconds slower, so we went with the lift.”
HEARD · CRITERION 6“We got the idea from a video.”
WITH SPECIFICS“The ratchet came from another team’s reveal video, which is on our Credit Summary. Theirs slipped on our lighter arm, so we made the pawl longer and tested 20 lifts with no slips.”
💡
The test: could a judge learn something from your answer that they couldn’t have guessed by looking at the robot? If not, add a name, a number, a source or a moment.

Common Gaps — and How to Close Them

Only robot talk, no teamwork stories

Criteria 4–6 stay “Not Yet Heard” or “Heard” even when the robot explanations are excellent.

Fix: prepare one real story each for “something a teammate taught me,” “a decision we made together” and “how we used an outside idea.”
Only the finished robot, not the journey

Criterion 2 asks what you tried, what failed and what changed.

Fix: list everything you tried, in order, as a team. Keep the failures in.
“We tested it” with no results

Testing without a count, time or measurement is “Heard,” not “Heard with Specifics.”

Fix: know one or two real numbers and what you changed because of them.
Explaining work you didn’t do

The person who did the work can give the specifics. Second-hand answers tend to stay general.

Fix: pass it to the teammate who did it (Section 4).
A prepared answer that misses the question

Practicing is fine. Answering a different question than the one asked isn’t.

Fix: prepare stories and evidence, not scripts. Listen, then answer what was asked.
// Section 06
Practice Tools
Question bank, randomizer, timer and self-check, all organized around the six criteria.
📌 Quick Take Spartan practice suggestion: run a mock three times before an event; this is not a judging requirement. Make sure every criterion comes up, especially the teamwork ones. Afterward, use the self-check to find which criterion still needs a specific story.

Mock Interview Timer

GRSF doesn’t set an interview length, and events vary. Practice short conversations so you don’t rely on having lots of time.

Question Bank

One person reads a question aloud, and the students who did that work answer. Questions marked GRSF are the official rubric sample questions. The rest are Spartan practice prompts. Judges can ask in any order and with any wording.

Question Randomizer

Each topic has several wordings, and the randomizer picks a different one each round. Your team practices answering the idea, not reciting a script.

Press Start to begin
One person asks the question. The students who did that work answer, and teammates add on.

SPARTAN RECOMMENDATION Practice tools only. They don’t predict an official score.

Rubric Self-Check

OFFICIAL Criteria from the GRSF Team Interview Rubric. GRSF also publishes a student-friendly version for practice.

After a classroom mock, mark unasked or interrupted rows as Pending. Before selecting 0, ask the relevant official sample question: 0 means the team still could not address the row; 1 means a general answer; 2 means concrete details. Follow-up details count fully. These practice observations are not predicted official scores. Do not enter confidential event judging records here.

If Judges Come Back

  • Judges sometimes return to a team to hear more or to fill in a criterion. Treat it like the first conversation.
  • They’re trying to hear more, not to catch you out. Same rules: students answer, and notebook and robot are references.
  • Have the students who did the work available, for example whoever wrote the code if programming comes up.
// Section 07
Event Day
Being ready when judges reach your pit, what to do during the conversation, and the debrief afterward.
📌 Quick Take Interviews start early and continue all day, so judges may arrive at any time. Keep the notebook, summaries and robot at the pit, and keep the students who can tell your stories nearby. Afterward, debrief while it’s fresh.

STEM
Communication as Engineering
Engineers explain their work to people outside their specialty throughout their careers. They describe what they tried, what the data said, who they worked with and where an idea came from. The judge interview practices exactly that, with real work, in your own words.
