OK - so tests are used once a term at your school (as at ours) - as some form on independent check on your observations of pupil performance I presume.
What are you telling parents?
Do you report NC LEVEL attained and next target - i.e. Johnny is currently working at 2b and his target is 2a, here's a handout showing you the kinds of things he needs to be moving on to doing in maths/ English (reading/ writing).
Do you even consider this as something you should be doing?
Or do you just give parents information on performance at end KS1 (Teacher Assessed KS SATs results) and end KS2 (both results & teacher assessments at KS2 SATs)?
Excluding the novel of the English primary school report card teacher's seem enamored of (much text saying very little indeed - although there is a code - spirited = difficult/ lively = can't sit still/ popular = forever gabbing away in class) what kind of feedback are you given parents which substantively informs them that their child is struggling/ doing well/ doing fabulous in core subjects: Science/ Maths/ English (reading/ writing)/ History/ Geography/ etc...
I ask this in the context of a parent who has serious doubts that the old national curriculum was fully delivered at their child's school, who is aware that Y6 was spent entirely on English/ Maths in the run up to KS2 SATs until now and who has no evidence in my possession from 7 years of education at St. Mediocre of what work is being done in school.
Out of curiosity - do teaching unions consider professional standards an issue? Or is it just about pay/ conditions?
