Texas Education Code - EDUC § 21.4045. Planning and Noninstructional Duties of Teachers

(a) A school district may enter into a supplemental agreement with a classroom teacher under which the teacher agrees to perform a duty relating to initial lesson plan design or instructional material selection that is not a duty generally:

(b) A school district may not require a classroom teacher for a foundation curriculum course to spend planning and preparation time to which the teacher is entitled under Section 21.404 creating or selecting instructional materials to initially cover the applicable essential knowledge and skills for the course unless the teacher has entered into a supplemental agreement described by Subsection (a). This subsection may not be construed to prohibit a classroom teacher from choosing to spend the teacher's planning and preparation time creating or selecting instructional materials.

(c) A supplemental agreement between a school district and a classroom teacher described by Subsection (a) under which a teacher is assigned responsibility for a greater number of duties unrelated to providing instruction than other full-time teachers of the same grade level in the district must explicitly state each of the teacher's duties unrelated to providing instruction.
