Mae Deddf Addysg 2002 yn cynnwys gofyniad statudol i ysgolion annibynnol penodol gofrestru â Gweinidogion Cymru a chael eu harolygu gan Estyn. Yr ysgolion annibynnol sy'n gorfod cofrestru yw'r rheini sy'n darparu addysg lawn-amser i 5 neu fwy o ddisgyblion o oedran ysgol gorfodol neu sy'n darparu addysg ar gyfer o leiaf 1 disgybl o’r oedran hwnnw sydd â datganiad AAA. Fodd bynnag, nid yw'n ofynnol i'r staff addysgu a'r rheini sy’n cefnogi dysgu yn yr ysgolion hynny gofrestru gyda Chyngor y Gweithlu Addysg. Ystyrir bod ysgolion annibynnol yn fusnesau preifat neu'n fentrau elusennol ac nid oes yn rhaid i athrawon sy'n gweithio mewn ysgolion o'r fath feddu ar Statws Athro Cymwysedig.
The Education Act 2002 places a statutory requirement for certain independent schools to be registered with the Welsh Ministers and inspected by Estyn.  The independent schools that have to register are those which provide full-time education for 5 or more pupils or which provide education for at least 1 pupil of that age for whom there is an SEN statement.  However, there is no requirement for the teaching and learning support staff in those schools to register with the EWC.  Independent Schools are considered private businesses or charitable enterprises and the teachers working in such establishments are not required to hold Qualified Teacher Status (QTS).
