Aim for 200: One Eedi quiz each week

Two independent trials of Eedi found that maths gains were largest among pupils who completed more questions.

We recommend schools aim for 200 completed Eedi questions per pupil across the school year.

With five questions per quiz, this means completing 40 quizzes—roughly one per teaching week.

The goal is helping every pupil finish the quiz, not just setting it.

‍

Why 200?

Every Eedi question is diagnostic, identifying the specific misconceptions behind wrong answers.

A quick dashboard check gives you a targeted class-level list of what to reteach next lesson.

Unfinished quizzes provide no data, making weekly completion essential for effective feedback.

One quiz a week: set, check, catch up

1. Plan. Pick a fixed weekly slot (e.g., Tuesday homework) to make expectations clear for pupils.
2. Check. Use the dashboard to see completion rates and identify prevalent misconceptions.
3. Catch up. Provide an in-school slot like form time for pupils who miss a week or lack home internet.

A concrete version: quiz set as Tuesday homework, dashboard check on Thursday, and anyone who has not completed it does so in Friday form time. Adapt freely, of course!

Break it down: 7 quizzes per half-term

Managing the target is simple when broken down: aim for 7 completed quizzes per half-term.

This structure ensures students clear over 200 questions by summer without extra workload.

Using the end of each half-term as a natural "pit stop" keeps the momentum going. It’s a quick, low-admin way to ensure everyone stays on track, making the goal feel recoverable and preventing any stressful end-of-year scramble.

‍

Build a "200 Club" culture

Build student buy-in by framing the target as the "200 Club" to celebrate shared classroom wins.

A visual tracker or weekly shout-out makes "what on-track looks like" clear to everyone.

By setting a routine slot and a quick dashboard check, you can spot the pupils who are drifting early on. This way, you make sure one gets left behind while there’s still plenty of the year left to support them.

For readers who want the research detail

The recommendations draw on two trials evaluated by WhatWorked Education:

• School-level trial: 20 schools using NWEA MAP Growth; overall one-year estimate d = 0.17.
• Class-level trial: 2,296 pupils; pupils completing at least 200 questions showed an exploratory estimate of g = 0.24.
• Caveat: These are nested compliance estimates describing associations within the trials, not direct causal effects.
