We took a deep dive into five weeks of data from one school using Fruitify, an AI-supported assessment system designed to provide task-linked feedback on extended written responses, and the results are crystal clear: when teachers gave structured, timely feedback using Fruitify, student performance really took off and stayed high!
Key outcomes:
📈 14.2 percentage point increase in attainment within one week
📊 15% total improvement over five weeks
📉 22% reduction in attainment gap (standard deviation)
✅ Statistically significant impact (p = 0.0087)
🔁 Sustained improvement across new topics — not a short-term spike
The difference was simple but powerful: pupils received actionable feedback much faster using Fruitify than they would usually.
The result was not just higher averages but greater consistency across the class.
The Starting Point
To get a good starting marker, pupils answers were loaded into Fruitify for two weeks, in which they averaged 45.2 % and 41.8 % in Week 1 and Week 2 respectively, with a notable and wide attainment spread between top and bottom performing students.
The Intervention: Shortening The Feedback Loop
Between Week 2 and Week 3, the teacher introduced timely, actionable feedback through Fruitify.
Instead of:
- A mark/score days or a week later
- General comments
- Moving on to the next topic
Pupils received:
- Timely, actionable feedback on what went well
- A personalised evaluation that is structured, and linked to Assessment Objectives
- Clear next steps for improvement
Feedback stopped being retrospective and became enlightening.
The Impact: In One Week
The class then repeated the same assessment, and one week later:
- Class average rose from 41.8% to 56.0%
- A 14.2 percentage point increase
- Statistical significance confirmed (p = 0.0087)
In practical terms, the improvement was highly unlikely to be random.
The feedback changed outcomes.
The Strategic Finding: Closing The Gap & Raising The Bar For All
What matters for Trust leaders is not just uplift; it’s sustainability, and ongoing improvement.
Over Weeks 4 and 5, as pupils moved onto new content:
- The class average climbed further to 60.2%
- A 15% total increase across five weeks
- The attainment gap narrowed by 22%
This wasn’t a short-term spike. Or a case of practice makes perfect on one assignment/ question when repeated. The feedback intervention actually created a new, higher baseline of performance.
Lower-attaining pupils made the strongest gains, which demonstrates how fast, actionable feedback can help level the playing field for SEND pupils, who are often held back by working memory and anxiety issues.
Why This Matters at Trust Level
For teachers, schools and leaders with Multi-Academy Trusts, three strategic implications stand out:
- Feedback timing directly affects attainment: When students receive and act on feedback immediately, understanding stabilises before misconceptions embed.
- It reduces variability, not just raises averages: Closing gaps improves predictability of outcomes – critical for trust-wide performance oversight.
- It improves impact without increasing marking burden: Using Fruitify did not require additional teacher hours, on the contrary, it reduced marking burden and delivered smarter, more timely feedback.
The Big Question
If one class can increase attainment by 15% over five weeks by shortening and improving the feedback loop, the question becomes what this might look like for a whole school or Trust.
In this trial, reassessment was made feasible within the same learning cycle without requiring additional marking time — allowing pupils to act on feedback before moving on to new content.
As the class progressed to subsequent topics, the improvement in performance was sustained, suggesting that acting on feedback immediately may support a more stable understanding of assessment objectives across future work.
Applied consistently across subjects, this approach may offer a pathway towards Trust-wide improvements in attainment.
