The Texas Education Agency launched the Grow Your Own (GYO) grant program in 2018 to encourage districts to develop or expand existing high-quality education and training courses for high school students and to support district-employed paraprofessionals (including instructional aides and long-term substitute teachers) to pursue certifications that would allow them to enter full-time teaching roles. This study aimed to help state education leaders in Texas understand the progress of districts in implementing the GYO program and the early outcomes of participants. This study analyzed data from 2015/16 through 2020/21 for districts that received GYO funding in the first two grant cycles and districts in the same geographic locales within the same regions that did not receive GYO funding (comparison districts). The study found that the majority of districts awarded a GYO grant were in rural areas and small towns. This document presents the following four appendixes that accompany the study: (1) About the Texas Grow Your Own grant program; (2) Methods; (3) Supporting analysis; and (4) Supplemental analyses.
