California Code, Education Code - EDC § 33126.2

(a) The Superintendent may recommend additional data elements for inclusion in the Academic Performance Index.  Data elements may be incorporated in the Academic Performance Index only after those elements have been determined by the state board to be valid and reliable for the purpose of measuring school performance, and only if their inclusion would not be likely to result in a valid claim against the state for reimbursement pursuant to Section 6 of Article XIII B of the California Constitution.

(b) The Superintendent shall additionally review, and the state board shall consider, any empirical research data that becomes available concerning barriers to equal opportunities to succeed educationally for all California pupils, regardless of socioeconomic background.  Upon obtaining this information, the state board shall evaluate whether there is any need to revise the school accountability report card.
