Fodd bynnag, os na fydd ysgol annibynnol yn cymryd camau i ddiogelu a hyrwyddo lles plant sy'n ddisgyblion yn yr ysgol mewn ffordd sydd, ym marn Llywodraeth Cymru a chyrff eraill, yn briodol, byddai modd tynnu'r ysgol o'r gofrestr ysgolion annibynnol yn y pen draw.  Byddai hyn yn golygu nad yw'r ysgol yn cael cynnig addysg lawn-amser bellach.
However, in the event that an independent school does not act to safeguard and promote the welfare of children who are pupils at the school in a way that Welsh Government and other bodies think is appropriate, the ultimate sanction would be to remove the school from the register of independent schools.  This would mean the school could no longer offer full-time education.
