Abstract: The Creative Achievement Scale (CAS) was designed to measure the creative accomplishments of deceased individuals based on information extracted from biographical sources (e.g., published biographies). The CAS contains 11 items which pertain to personal attributes, product qualities, and sociocultural factors. Statistical analyses conducted on one small (n = 12) and one larger sample (n = 50) of subjects revealed the CAS to be a reliable and valid instrument.
