At Kings River Community College, analyses were conducted of the grades and characteristics of students in Mathematics A (Elementary Algebra), Mathematics B (Plane Geometry), Mathematics C (Trigonometry), and Mathematics D (Intermediate Algebra) to determine which variables were significantly related to student success. Data were gathered on 69 students in Mathematics A, 24 in Mathematics B, 15 in Mathematics C, and 64 in Mathematics D regarding placement test scores, high school grade point average (GPA), prior college units taken, prior college GPA, high school mathematics grades, and prior college mathematics grades. Findings of the study include the following: (1) students had less than a 50% chance of success in Mathematics A if they scored below the 49 percentile on any mathematics placement test, had less than a 3.0 high school GPA, less than a 3.25 GPA in prior college courses, or had grades below A or B in prior college math classes; (2) grades earned in high school math classes had no bearing on success in Mathematics A; (3) the only significant success factor in Mathematics B was college GPA; (4) in Mathematics C, no factor was found to be significant in determining success or failure; and (5) Mathematics D students had less than a 50% chance of success if they scored below the 56 percentile on placement tests, had less than a 3.0 high school or 2.9 college GPA, and had taken less than 35 college units.
