The Tenney School has maintained accreditation through Cognia (formerly the Southern Association of Colleges & Schools) since 1979. The accreditation process is repeated every five-to-six years. The last School Accreditation Engagement Review of The Tenney School was successful completed in February 2022.
In Texas, all approved accrediting organizations post their member schools on the TEPSAC website (Texas Private School Accreditation Commission). Parents can check for any private school accreditation, including The Tenney School, on this site.
