To address these issues, we introduce subpool partition strategies for item selection and within-person statement exposure control procedures. Simulations showed that the multinomial method reduces computation time while maintaining measurement precision. Both the freeze and revised Sympson-Hetter online (RSHO) methods controlled the statement exposure rate; RSHO sacrificed some measurement precision but increased pool use. Furthermore, preventing a statement's repetition on consecutive items neither hindered the effectiveness of the freeze or RSHO method nor reduced measurement precision.1 aChen, Chia-Wen1 aWang, Wen-Chung1 aChiu, Ming, Ming1 aRo, Sage  uhttps://onlinelibrary.wiley.com/doi/abs/10.1111/jedm.12252
