I'm looking to go back into teaching after five years out and I'm trying to get my head round how progress tracking works these days. Would be really grateful for some pointers on how secondary schools track progress and identify underachievement without Levels at KS3? Is Midyis and Yellis still used? Are there any other tracking systems widely used? Any recommendations where I can read up on up to date assessment / tracking issues? Many thanks for any help.
