TTU K–12

TTU K-12 is an approved learning school from kindergarten through twelfth grade program in Texas, offering high school diplomas. It is operated by Texas Tech University, which is located in Lubbock. TTU K-12 offers individual courses (supplemental), credit by exams (CBEs), homeschool curriculum, bulk testing services, and a full-time Texas Diploma Program that includes high school, middle school and elementary school.

History
TTU K-12 was established by legislative and state board action in 1993 as a "Special Purpose District" designed to educate students with special circumstances and whose educational needs were not adequately met by traditional schools. In 1998, the Commissioner of Education granted expansion of the program to include kindergarten through 8th grade. TTU K-12 now serves students in kindergarten through 12th grade.

Enrollment
In 1994, the first graduating class from TTU K-12 consisted of only two students. Now, TTU K-12 has a total enrollment of around 1,500 full-time students among high school, middle school and elementary school students. TTU K-12 graduated more than 300 students in the class of 2017-2018 and had served more than 415,000 students in over 70 countries by the end of that academic year.

Students can enroll in courses through TTU K-12's full-time diploma-seeking program, where students take all the state-required courses and assessments to graduate. Upon graduation, students receive a Texas high school diploma.

Another option is the supplemental program. Students can catch up or get ahead by taking individual courses or credit by exams while still enrolled in their current school district.

Transfer credits
All credits earned through TTU K-12 are recognized by colleges and universities.

Accreditation
TTU K-12 is accredited by the Texas Education Agency (TEA). Courses and credit by exams (CBEs) are aligned with the Texas Essential Knowledge and Skills (TEKS). The high school courses are approved by the NCAA.
