DS (Year 8) has just sat some tests at school. He said that they were VR/NVR, Maths & English. I thought that they may be CAT tests but they did these in Year 7 but he said that they were called Midges Tests. I've never heard of these before - can anyone shed some light? Am I being a bit 
or are they just CAT tests by another name? The school didn't give any info as to when they were, DS just got told by his form teacher that they would miss x lesson to do them on x day. Thanks!
