We trace the origins of testing to its civil service roots in Xia Dynasty China 4,000 years ago, to the Middle East in Biblical times, and to the monumental changes in psychometrics in latter half of the twentieth century. The early twentieth century witnessed the birth of the multiple-choice test and a focus on measuring cognitive ability rather than knowledge of content – influenced greatly by IQ and US Army placement testing. Multiple-choice tests provided an objectivity in scoring that had previously eluded the standard essays used in college entrance exams. The field of testing began to take notice of measurement errors and strove to minimize them. Computerized Adaptive Tests (CAT) were developed to accurately measure a person’s ability with the fewest number of items. The future advancement of testing is dependent on a continued process of experimentation to determine what improves and what does not.
