11-18 comp Traditional KS3 curtailed about Easter time of Y9 for starting the first GCSE module. KS4 routes OCR Nationals (for voc kids) BTEC GCSE Science + applied science GCSE Science + additional science GCSE biology, chemistry, physics So we currently have more routes than you although these will soon be simplified to just BTEC GCSE Science + additional GCSE biology, chemistry, physics School in a nice area with lovely kids and 80% achieving 2 GCSEs then I can't see why you need the BTEC. No reason why they shouldn't be doing foundaton triple. Think about the KS4 routes in the context of their progression. What do your students go on and do afterwards? If you're 11-16 then Connexions should have this information somewhere. You need to make sure you are providing suitable progression routes for your students so those who want to take science further are able to but everyone has a base eg, if they decide to be a primary teacher they will need GCSE science.
