Garner Independent School District
Garner Independent School District is a public school district based in the community of Garner, Texas. Until the year 2021, Garner was the only school district in Parker County that taught prekindergarten through 8th grade, and students went to other districts to complete high school. The district had one school – Garner School – and about half of the school's students transferred to Garner from nearby school districts. Now Garner ISD features a full secondary program and will have its first high school graduates in the year of 2025.
In 2009, the school district was rated "recognized" by the Texas Education Agency.
