US Training Provider Outcomes (WIOA) sample
A 500-row sample of the RetrainMap US Training Provider Outcomes dataset: 70,088 programs from the U.S. Department of Labor WIOA Eligible Training Provider results (ETA-9171), cleaned into 51 descriptive columns (provider, program, credential, CIP and O*NET codes, cost, students served/exited/completed, completion %, employment 2 and 4 quarters after exit, median quarterly earnings). Suppressed cells are blank, never zero; percentages are 0-100. The data dictionary is included.
