Adults are faced daily with making financial decisions, some which are very difficult, therefore, more knowledge is necessary about personal finance to help adults make wise financial decisions. This study examined if there was a statistically significant difference in pretest and posttest scores from the Test for Financial Literacy (TFL) as well as the pretest and posttest scores from each of the three sections of the Behaviors, Attitudes, and Perceptions of Knowledge of Personal Finance (BAP survey). A gain score was used to identify whether statistically significant differences existed between group mean gain scores for 10th-, 11th-, and 12th-grade students who received instruction using the EVERFI: Financial Literacy for High School game-based learning program. The population studied consisted of 65 10th-, 11th-, and 12th-grade students from three different high schools within the same school district who were assigned to take the required one semester course in personal finance. The study found a statistically significant difference in using the game-based learning program to teach personal finance to high school students based on the gain score of the TFL with the independent variables of the control group (those who did not use the EVERFI: Financial Literacy for High School game-based learning program) and experimental group (those who did use the EVERFI: Financial Literacy for High School game-based learning program). The dependent variable was the gain score, along with the independent variables of student gender (being male or female) and students' ethnicity (Caucasian, Asian, Hispanic, and African American students). However, the study found no statistically significant difference in the gain scores on the BAP survey. [The dissertation citations contained here are published with the permission of ProQuest LLC.
