What do schools need to know about processing speed and intelligence?

Interpret speed in the context of the task

Performance may also depend on visual scanning, motor output, attention, familiarity and the testing conditions. Interpretation belongs within the wider assessment profile and the examiner's explanation, including uncertainty.

Compare how the pupil reasons when time pressure and copying are reduced. Check whether the bottleneck is reading the question, retrieving information, planning or recording. Provide thinking time, concise instructions and accessible materials while retaining an appropriate intellectual challenge. Do not assume that a slow written response means the pupil needs simpler ideas.

For example, compare a spoken explanation with the same concept recorded by hand and with an agreed alternative. Record accuracy, time and assistance. This can identify useful classroom adjustments without turning a single score into a fixed limit. Examination access arrangements require their own evidence and current rules; they do not follow automatically from the label “slow processing”.
