However, this also resulted in an extremely skewed distribution of item exposure rates. To counter this issue, they recommended the use of the a-stratification with b-blocking (ASB) method, which balanced item exposure very well but at the cost of compromising on the average test time reduction and increasing the error of ability estimation. Therefore, the current study investigated several alternative methods for item exposure control when using response time-informed MIC, of which the most promising technique was inversely weighting MIC by the expected response time centered around 1.3.
