See your school's chapter leader, who can bring this issue up with your principal. The DOE must provide teachers with a semester or year-long curriculum in all core subjects which are aligned with state standards. Curriculum means: (a) a list of content and topics; (b) a scope and sequence; and, (c) a list of what students are expected to know and be able to do after studying each topic.
Core subjects are: Math, Social Studies, English Language Arts, Science, Foreign Languages, and other subject areas named by the DOE and shared with the UFT. Core course curriculum should be supplied even in cases where the courses may be electives.
However, the sufficiency and the quality of the curriculum provided is not grievable.
Teachers may still voluntarily write their own curriculum, and if the DOE or a school administrator specifically requests a teacher to write a curriculum, there must be sufficient time given during the work day or paid time after school via per-session in order to do so.
