Why It Matters
Timed tests can disadvantage pupils with dyslexia or related needs. Pupils may understand the content but struggle with reading speed, writing fluency, or processing instructions quickly. Without extra time, test results may reflect speed rather than understanding. Providing extra time ensures a fairer measure of attainment, especially in high-stakes assessments such as SATs.
Causes or Underlying Processes
Pupils may need extra time due to:
Processing speed difficulties (taking longer to read, think, or respond)
Working memory load (holding and using information while completing tasks)
Reading and decoding effort (slower reading reduces time for answering)
Writing fluency challenges (slower handwriting or spelling retrieval)
These factors are common in dyslexia and can significantly affect performance under timed conditions.
Evidence-Based Support Strategies
Build a clear evidence base
Gather examples of unfinished work, timed assessments, and observed processing difficulties.
Use extra time consistently
Apply it in class tests as well as formal assessments. This builds familiarity and confidence.Combine with other adjustments
Extra time is most effective alongside supports such as rest breaks, reader support, or simplified layouts.Prepare for statutory assessments
Follow current guidance from Standards and Testing Agency and Joint Council for Qualifications where relevant.Monitor impact
Check whether extra time improves completion and accuracy.Communicate with staff and families
Ensure everyone understands why extra time is in place and how it supports the pupil.
FAQ
Who should receive extra time?
Pupils with evidence of processing speed or literacy-related difficulties that affect test performance.
How much extra time should be given?
This depends on need and assessment guidelines, but often ranges from 25% additional time.
Can pupils become dependent on extra time?
No. It supports access, not dependency. The goal is fair assessment.
Should pupils practise using extra time?
Yes. They should be familiar with it before formal assessments.
