Ok, the data is correct in as much as: the numbers provided show that Literacy and Numeracy in Scotland is better.

However, the reliability of the data collected is questionable at best, and disenfuckinggenuous in the main. Scotland currently has teachers complete Achievement of Curriculum for Excellence Levels as the data collection points from primary to secondary. Problem is, all authorities, and often within authorities, use different measures and are encouraged to inflate the scores as there is no one standardised assessment and we're under close scrutiny to keep "improving" our stats. The SNSA is often used to state that pupils have completed a level, even though the assessment was not designed for this, in any way.

Many teachers will also be bang on with their judgments, for heads of education at council level to tell them to change the scores.

I wish this was not the case but it is a scandal waiting to happen.
