The Alberta Teachers' Association recommends the following procedures to effectively deal with concerns. The process always begins by talking with the teacher.
Teachers have some latitude in how they deal with the curriculum.
Discuss any concerns you have with the classroom teacher. The teacher may be able to answer your questions. If you cannot resolve your concerns by talking to the teacher, the next step is to speak with the principal. A third step would be to speak to the superintendent or other appropriate central office personnel. Keep in mind that these individuals cannot change the provincial curriculum but they may be able to explain why certain materials are included.
