It is for individual schools to determine what data and information they collect in the context of the specific issues within their school and in compliance with data protection law.
Yr ysgol unigol sy'n penderfynu pa ddata a gwybodaeth y mae'n eu casglu yng nghyd-destun y materion penodol sy'n codi yn yr ysgol honno a thrwy gydymffurfio â chyfraith diogelu data.
