Seventh- through ninth-grade Leander ISD students will learn about human reproduction, sexuality and abstinence in a series of three-day classes, according to an LISD press release. The three-day learning block will be held at every LISD high school and middle school from Oct. 21-May 26, according to LISD. The course is part of the science program in seventh through eighth grades and health curriculum in ninth grade. The classes will be led by Austin LifeGuard, which, according to its website, "is apolitical and provides Austin area teens with medically accurate information and factual data about the risks, potential consequences and options regarding sexual activity." Learning material for the course may be previewed at a student's school library from 8:30 a.m.-4 p.m. weekdays, according to the release, or at Austin LifeGuard's website. Parents or guardians of LISD students may request a "parent preview" of the curriculum by filling out an online form at Austin LifeGuard. "All content has been reviewed by the Leander ISD School Health Advisory Council (SHAC) and is grade-level specific and developmentally appropriate," according to the LISD website.
