The Florida Legislature passed a bill that changed the placement methods for some incoming students to the Florida State College System in 2013. This analysis of state policy looks at Senate Bill 1720 as the treatment in an interrupted time-series trend study at one state college in Florida. This research attempts to answer three questions: (1) What is the enrollment trend over the last 10 years in first-level math courses, such as Intermediate Algebra (MAT1033), Liberal Arts Math (MGF1106), and Elementary Statistics (STA2023) for first time in college (FTIC) students? (2) What is the trend of course passing rates in the above listed gateway math courses before and after the developmental education requirements changed? (3) What are the trends in student success rates before and after the changes to developmental education requirements in these courses for various demographics, such as race, age, and gender, for FTIC students in these math courses? This study looked at one college's gateway math sequence in terms of enrollment and student success. The observed benefits to this institution were the gains in FTIC student enrollment in the gateway math courses. There were observed decreases in FTIC passing rates in the three gateway math courses, yet the total share of FTIC students taking and passing gateway math courses increased. This study should be shared with the Mathematics Department with the hope that it will continue to track student success in its courses and investigate other research in the area of gateway math instruction for younger post-secondary students as their enrollment continues to follow a decrease in the average student's age.
