Your result has two separate scores. Points say how much of the task your work got right. AI fluency says how you used the AI to get there. Both point back to something you actually did in the session.
Every participant gets the same built-in AI tooling, interface, and time for the duration of the assessment, at no personal cost. The assessment fee covers all AI usage, so participants who can't afford premium AI subscriptions aren't penalized. Where an assessment offers a choice of models, every participant sees the same list; the assessment creator can lock it to one model when a fair head-to-head on a single assistant matters more than choice.
What the report shows
Points and AI fluency are kept apart, and flags are for a person to review. AlgoArena does not recommend advancing or rejecting anyone. Once an assessment is published, its scoring stays fixed so results stay comparable.
On algorithm questions, hidden tests set the points. Pass half the tests and you get half of that question's points. Build and open-ended questions without tests are scored against the question's rubric. Written review comments explain the work and never change test points.
A separate score for how you used the AI: planning, prompting, verification, and agentic workflow. It never changes your points. A skill with too little evidence shows as Not measured, never as 0, and is left out. If no skill can be measured, AI fluency shows Not measured.
Pastes, tab switches, very little typing, and similar signals are flagged for a person to look at, with the replay. Flags never change either score.
The organizers may set their own pass mark on points. It reads points only, never AI use or flags. Without one, the report shows scores only.
AlgoArena does not recommend advancing or rejecting anyone. The organizers make that decision.
The AI fluency weights were set by experts and are awaiting calibration on real cohorts. AlgoArena does not describe them as independently validated or universally predictive.
Each one is scored from 0 to 100. Problem solving is mostly your points as a percent, plus code quality and the edge cases you named in your own typed work. AI fluency is the average of the other four, on questions that allowed AI. A competency is scored only when the session shows enough of it. Otherwise it reads Not measured, never 0. Verification comes from what you did after each change: ran it, edited it, undid it, or read it. On questions with no AI, planning and verification read your own work, and they do not count toward AI fluency there.
Your assessment session is recorded and replayable. Both the scoring and the people reviewing your work read that record.
The session is recorded and replayable
Editor activity, file changes, and timing are captured so an evaluator can replay how the work happened instead of guessing from the final code.
AI conversations
Every prompt you send, the reply it produced, and which suggested edits you kept or rejected.
Verification runs
Test runs and automated checks, along with their results.
Keystroke activity
In the code editor, counts and timing only, not which keys you press. In your app preview, the text you type into its fields and the keys you press are recorded for the replay. A password field is never stored.
Integrity signals
Pastes, tab switches, window focus changes, and whether a second monitor is connected.
Who can see it
The organizers who invited you to the assessment, and authorized AlgoArena operators when needed to run or support the service. We do not sell assessment data. Retention and other uses are described in the participant notice and Privacy Policy.
Points on algorithm questions come from hidden tests, so only working code earns them. AI fluency skills are scored from what you actually did in the session. Padding keystrokes or prompts will not raise either score. The best strategy is to direct AI well, check the work, and ship what was asked.
Every participant gets built-in frontier AI at no personal cost, with the same interface, timer, and tooling for everyone. Some assessments let you pick from a short list of models; otherwise the organizers lock one in. Do your AI work in that built-in chat, not an outside tool. We can only measure the planning, prompting, and verification we can see, so work done in an outside tool does not count toward those skills. Large pastes are flagged for a person to review. They never lower your points.
Yes. We track code changes, keystroke activity in the code editor (counts and timing, not which keys you press), what you type and press in your app preview, AI prompts, test runs, tab switches, paste events, whether a second monitor is connected, and timing. The session is recorded and replayable, and that record is what the scoring draws on. It is shared with the organizers who invited you. We do not sell assessment data. The participant notice and Privacy Policy explain retention, service operations, and other permitted uses.
You get two separate scores. Points say how much of the task your work got right. AI fluency says how you used the AI, or Not measured when there was too little to go on. Evaluators see the evidence behind each one. These are evidence-linked aids for a human decision, not a claim of psychometric validation.
Only when the assessment includes an algorithm question, and then hidden tests set its points. The main signal is AI-native delivery: planning, directing agents, checking output, recovering from mistakes, and shipping working software.
Some people dictate, use assistive tools, or write in their own editor and paste. Very little typing never lowers your points or your AI fluency score. It adds a note for a person to check in the replay.
No. AlgoArena shows scores and flags, and does not recommend advancing or rejecting anyone. The organizers decide. They may set their own pass mark on points, which reads points only.
