On 30 September 1924, the Reichsausschuß für Arbeitszeitermittlung, the Reich Committee for Determining Working Time, was founded. It is known by its initials, REFA. Its early task was to measure working time for cost calculations and for piece-rate work. REFA trained Zeitnehmer, time takers. By 1929 REFA had trained 1,650 time takers, and by 1943 about 12,000. The association still exists and still trains people in work-time study.
