A method includes providing user interfaces from a server to present questions to a plurality of test takers. For each question and each test taker, an elapsed time is recorded and the elapsed times are used to set a boundary time between groups of response times for each question. User interfaces are then provided from the server to present the questions to an additional test taker. For each question, a response is received and a response time is determined. The response time, the received response and the boundary time of each of the questions are then used to determine a score for the additional test taker that has more precision than using the received responses alone to determine a score for the additional test taker.
