Kris a background of ECC is valuable, because other populations may not have similar results4Background CurriculumMth090Pre-AlgebraMth099

CombinedBasic &Intermediate AlgebraMth096Basic AlgebraMth098Intermediate AlgebraMth097GeometryTransfer Level Math CoursesKris As a frame of reference. Not every college/state has this same sequence. We should also note that until recently, all transfer level courses in Illinois had to have at least an Intermediate Algebra pre-requisite, which is why we started our investigation there.5Background CurriculumDevelopmental Math CoursesMth101QuantitativeLiteracyMth102Gen.

We have not investigated other courses, primarily because our largest-enrolled courses are the developmental sequence (roughly have of our students) and the four entry-level transfer courses.6Background PlacementCOMPASS ExamWritten by ACTCalculators allowedCan be retaken onceCan place students up through Calculus I4 DomainsBranchingPre-AlgebraCollege AlgebraTrigonometryAlgebraStartKris Some use Accuplacer, so this background is valuable. Also emphasize the branching nature of the test. If you dont do well on the initial Algebra portion, you drop down to Pre-Algebra and can never improve your score.7College ReadyArithmeticPre-AlgebraBasicAlgebra0-2021-4344-100ArithmeticPre-AlgebraBasicAlgebraCollege ReadyBasicAlgebraInt.
