CAMPUS DISTINCTION DESIGNATIONS.

(a) The commissioner shall award a campus a distinction designation for outstanding performance in improvement in student achievement if the campus is ranked in the top 25 percent of campuses in the state in annual improvement in student achievement as determined by the commissioner.

(b) In addition to the distinction designation described by Subsection (a), the commissioner shall award a campus a distinction designation for outstanding performance in closing student achievement differentials if the campus demonstrates an ability to significantly diminish or eliminate performance differentials between student subpopulations and is ranked in the top 25 percent of campuses in this state under the performance criteria described by this subsection. The commissioner shall adopt rules related to the distinction designation under this subsection to ensure that a campus does not artificially diminish or eliminate performance differentials through inhibiting the achievement of the highest achieving student subpopulation.

(c) In addition to the distinction designations described by Subsections (a) and (b), a campus that satisfies the criteria developed under Section 39.204 shall be awarded a distinction designation by the commissioner for outstanding performance in academic achievement in English language arts, mathematics, science, or social studies.

(d) In addition to the distinction designations otherwise described by this section, the commissioner may award a distinction designation for outstanding performance in advanced middle or junior high school student achievement to a campus with a significant number of students below grade nine who perform satisfactorily on an end-of-course assessment instrument administered under Section 39.023(c).
