19 Tex. Admin. Code § 33.2
Each year, the State Board of Education (SBOE) shall determine whether a distribution to the Available School Fund (ASF) shall be made for the current state fiscal year. The SBOE shall determine whether such distribution is permitted under the Texas Constitution, Article VII, §5(a)(2). The annual determination for the current fiscal year shall include a projection of the expected total return of the Permanent School Fund (PSF) at the end of the current fiscal year and the realized returns during the nine preceding state fiscal years. Any one-year distribution to the ASF shall not exceed 6.0% of the average market value of the PSF, excluding real property managed, sold, or acquired under the Texas Constitution, Article VII, §4, as determined under the Texas Constitution, Article VII, §5(a)(1). When adopting the rate of distribution, the SBOE shall strive to balance the needs of current and future generations of Texas school children by attempting to maintain consistent levels of distributions per student and assets per student, after adjusting for inflation.
