Maturity must match ability
There is a case for sweeping away all inhibitions on pupils sitting exams when they and their teachers feel they are ready. But we do not want in Scotland the spectacle of short-trousered prodigies paraded before the cameras as they take up a place at university. Maturity is not just a matter of intellectual capability.
The 5-14 programme ought to be able to cope with the ablest pupils. That is why level F is being introduced and there is no reason why a teacher cannot take an exceptionally bright pupil well into, even beyond, the Standard grade syllabus while still under 14.
From S3 to S6 exams should be taken when pupils are ready, although the practical difficulties for school staffing should not be underestimated. Candidates aiming at Advanced Highers, which are bound to become a benchmark for oversubscribed university courses, need as much time as they can find.
The Government's proposed compromise of a year's flexibility in when exams are taken is acceptable for the time being. Once Higher Still with its five levels is bedded down, there may be scope for further changes.
