Transfer rates Transfer rates are very high in the United States with 60% of all
bachelor's degrees being awarded to students that began their college at another institution. Some transfers are planned; many
community colleges have
articulation agreements with four-year colleges. Other university systems are
college-preparatory schools, which offer the first two years of the degree at a local campus with transfer into the
flagship university in the junior year.
Factors affecting persistence Grades Grades earned in a student's first semester are a strong predictor of student persistence. In a Budny longitudinal study of Purdue engineering students, it was shown that first semester GPA was a better predictor of retention than SAT scores. In the study, first semester engineering students who earn an A grade in Precalculus have the same persistence after 6 semesters as students whose first semester mathematics course was Calculus I and who earned a B, and these levels of persistence are also equivalent to students whose first semester course was Calculus II, and who earned a grade of C. A second study on the role of grades in first semester coursework supports the importance of first semester GPA, showing that the grade earned in English and mathematics courses are a strong predictor of persistence after one year, with the strongest predictor of returning corresponding to earning a grade of "A" in English, and the next strongest predictors corresponding to earning a "B" in English, or an "A" or "B" in mathematics. The level of course taken (for example, whether Calculus I or Precalculus) is less of a predictor of persistence at university than the grade earned in the mathematics class taken. This consideration is important for students who might, for example, have earned a passing
AP Calculus AB score of "3" (as opposed to a higher score). For
STEM majors that rely on Calculus I as a prerequisite, (e.g. engineering, physics and chemistry majors), these students with an AP AB score of "3" might consider retaking Calculus I their first semester at university and earning a high grade while also solidifying their calculus knowledge, and then taking Calculus II in their second semester.
Cost of tuition The economy also has a noticeable effect on retention rates. The cost of public and private institutions in the 1999–2000 school year, which includes tuition and on campus housing, averaged $7,302 and $20,277, respectively. After adjusting for inflation, this represented a 22% cost increase at public institutions and a 27% increase at private institutions for the 10-year period between the 1989–1990 and 1999–2000 academic years. According to the
National Center for Public Policy and Higher Education, tuition at a 4-year college represented 12% of the total income for families that fell into the lowest income bracket in 1980, and rose drastically to encompass 25% of their income by 2000. This has created an influx of part-time students and working students. In the undergraduate population, 50% of students describe themselves as working primarily to pay for their education at an average of 25 hours per week. This leaves working-class students little time to become involved on campus and actively participate in university life. According to the U.S. Department of Education,
National Center for Educational Statistics, only 50% of those who enter higher education actually earn a bachelor's degree. Depending on the university, there are resources in order to help those with financial issues, such as financial aid. == Addressing student retention ==
