STIMA
Stima Prova · The post-AI skill assessment

Work with the machine.Prove the human.

Stima Prova turns the assignment or take-home you already use into an AI-allowed session, grading the work on your rubric and the AI use on a published scale, every score cited to the record.

The problem

Everyone already works with AI.Almost nothing measures how.

The polished submission used to be the signal. In a post-AI world, the signal moved into the process, where nobody can see it.

83%

Candidates would use AI if allowed

And 14% admit they already do. Banning it doesn't remove AI from the take-home; it just removes it from your view.

HACKERRANK CANDIDATE RESEARCH

66%

Leaders won't hire without AI skills

The requirement is universal, the standard doesn't exist, so every interviewer improvises their own probe, and transcripts say nothing.

False positives from AI detectors

Of essays by non-native English writers, falsely flagged as AI-written. Detection punishes the wrong people and explains nothing.

The result: people learn to hide AI use, not to use it well.

How it works

From the work
you already use
to graded evidence.

01

Adapt

Bring one assignment or role question. We reshape it with you, same goals, same rubric, plus a planted difficulty a blind copy-paste gets wrong.

02

Session

The person works one focused, timed session with AI explicitly allowed, recorded with consent. No video recording. No lockdown browser.

03

Two scores

The work, graded on your rubric. The process, graded on a published scale. Every score cites a moment in the session record.

04

Confirm

A human confirms every outcome before it counts. Grades and decisions export as CSV for your LMS or ATS, with a paper trail you can defend.

The AI-collaboration scale

Three levels.Higher is not better.

The scale reads how much thinking was handed to the model, prompts, edits, verification, model switching, time. The grade is calibration: the observed level against what the task demanded.

Pick a task · the right level changes

This task calls for Operator Verifiable and routine, but the spec has teeth. Iterate against the requirements and spot-check the output.
Level 1

Delegator

Hands work to AI

Restates the brief, accepts the first answer. Right for verifiable, low-stakes work.

Level 2

Operator

Works with AI

Iterates, corrects, edits substantively. The right default for mixed, everyday work.

Level 3

Director

Leads the work

Sets the approach first, verifies the parts most likely wrong, owns the outcome.

Calibrated, matched the task Near · one step off Under-directed · handed off judgment Over-directed · controlled what AI could carry

Two rooms it changes

One platform.Pick your world.

Trust & privacy

No proctoring. No prohibition.No black boxes.

Consent-first recording

Workspace-only. No video recording, no keystroke logging, no lockdown browser. Participants see exactly what is kept before they start.

Humans confirm outcomes

Every outcome is confirmed by a person. Low-confidence results route to a reviewer, and participants can dispute.

Your rubric stays yours

Your criteria grade the work; the collaboration scale is added alongside, never instead. Results stay comparable across courses and roles.

Data handling with care

FERPA-aligned for campuses, hosted in the EU, DPA on request, no training on your data. Built to WCAG 2.1 AA.

The founding cohort is forming now

Teach one assignment.Run one role. This term.

Built by a project management instructor and former group product manager at Arizona State University. Bring the work you already use, we do the redesign with you and hand you the evidence.
