|(a) A teacher whose performance meets one of the following circumstances will be designated as a "teacher in need of assistance": (1) a teacher who is evaluated as unsatisfactory in one or more domains; or (2) a teacher who is evaluated as below expectations in two or more domains. (b) When a teacher is designated as a teacher in need of assistance, the certified appraiser and the campus principal or designee shall, in consultation with the teacher, develop an intervention plan that includes the following: (1) domain(s) that designate a teacher as a teacher in need of assistance; (2) directives or recommendations for professional improvement activities; (3) evidence that is used to determine successful completion of professional improvement activities; (4) directives for changes in teacher behavior; (5) evidence that is used to determine if teacher behavior has changed; and (6) specific time line for successful completion. (c) In cases when the teacher's appraiser is not the teacher's principal, the principal shall be involved in the development and evaluation of the intervention plan. (d) A teacher who has not met all requirements of the intervention plan for teachers in need of assistance by the time specified may be considered for separation from the assignment, campus, and/or district. (e) The intervention plan shall include options for professional development activities designed to enhance teacher proficiency. At least one option shall not place significant financial burden on either the teacher or the school district. (f) An intervention plan may be developed at any time at the discretion of the certified appraiser when the certified appraiser has documentation that would potentially produce an evaluation rating of "below expectations" or "unsatisfactory."
