The president of the School Trustees Association has reminded more than 600 trustees they must stick to the law.
The association is holding its annual conference in Christchurch and celebrating 21 years since the reforms that introduced school boards of trustees.
Association president Lorraine Kerr told the conference trustees have legal obligations under a variety of Government acts.
She also mentioned the national standards in reading, writing and maths, saying only a vocal minority oppose the standards.
Ms Kerr later told Radio New Zealand News that boards are not in a difficult position with the standards.
She says problems with the standards are being worked through and she does not expect them to be an issue at the conference.
