This study provides the results of a latent class analysis (LCA) using data from the Trends in International Mathematics and Science Study -- 2011 (TIMSS-2011) with a focus on the 8th grade mathematics section. The study presents the analysis of item data with Mplus 7.31 to determine if results obtained yielded distinct latent subgroups. The data set used in the study was from four diverse countries (Turkey, U.S., Finland, and Singapore) participating in TIMSS-2011. Analyses yielded results suggesting three classes provided the best fit to the data. Class were statistically significantly associated with nation, and nation was associated with overall test performance. Results support prior work in which identification of multiple classes leads to potential questions regarding the construct validity of TIMSS-2011 8th grade mathematics test.
