Source and date: U.S. Department of Labor, Training Provider Results — the open program index behind trainingproviderresults.gov, snapshot taken 2026-09-02 (3,266 programs for California in the index that day); the site states the data cover programs approved as of June 30, 2025 and outcomes for July 1, 2021 – June 30, 2025. Cost is Out-of-Pocket Cost for a Non-WIOA Participant: Tuition and Requested Fees (DE111) where the provider reported it, otherwise Average number of dollars the training program received from each WIOA participant Individual Training Account (ITA) during the time period (DE138/DE135) — the basis is printed under each figure; books and supplies are added only when reported separately. “Completed” = Percent of All Students who completed the program (DE122/DE121); “Employed Q2” = Percent of All Students Exiters who were employed in the 2nd Quarter after Exit (DE123/DE129); “Median earnings” = Median Earnings in the 2nd Quarter after Exit of All Students that are Employed in the 2nd Quarter after Exit (DE125) — one calendar quarter, not a year.
