The multichoice scheme I proposed would be a national one and part of it would be a detailed analysis of the areas of the curriculum a child was weak on. There would be no point in a system that didnt give that detailed info - you and I obviously know that.
There are CD ROM or web based exam practice products that already do this type of analysis - it really is not rocket science.
A good teacher would know already, but what if the teacher does not know? Not all teachers are good. Some minority are bad or do not care and many more are simply overburdened. This would make life a lot easier for teachers.
An independent national multi-choice exam lasting say 45 minutes for each core subject and done once a term over say the last 4 years of a childs Primary education would surely give teachers (at both Primary and Secondary level) and parents a really good basis for a discussion about the future educational needs of the child, where they should be setted or streamed and what extra help they might need.
I dont want external moderation, it is far too imprecise and costly. I want one exam per term that cannot be manipulated, completley consistent and is taken completely outside the teachers hands. The teachers skill and time should be spent in designing a teaching programe in response to the data fed back for each child which should then be shared with the parent and child.
Taking the exam every term would also allow a teacher to spot if the performance of a child had suddenly dipped/risen compared to the last exam they took. This would also get round the problem of teachers feeling they were being unfairly judged when they have a weaker set of children. The progress comparison for each child would only be against the last test the child took. Not against the class, school or national average.
All of this exam process could be automated, with no marking or results reporting/analysis required of the teacher.
