fact that these public-private differences decline somewhat when six-year rates are used
suggests that students in the public colleges and universities are taking longer to
complete their degrees (see Table 2).

Effects of academic preparation
The chances of completing college in four or six years varies widely according to
the student’s level of academic preparation. Those who earn an A or A-plus grade point
average in high school have four and six-year completion rates of 58.2% and 77.5%,
respectively, compared to rates of only 8% (four-year) and 20% (six-year) for those with
C averages in high school. Similar differences are found with scores on standardized
college admissions tests: Among students whose composite score on the SAT is at least
1,300, four and six-year completion rates are 62.3% and 76.5%, respectively, compared
to only 18.2% and 39.8% for students whose composite score is less than 800.
The largest differences are observed when school grades and test scores are
combined: students with A averages and scores of 1,300 or above have four and six-
year completion rates of 68.9% and 82.6%, respectively, compared to 7.8% and 20.4%
for students with C averages and test scores below 800.
The data in Table 2 suggest that it would be unwise, and possibly misleading, to
compare the raw degree completion rates of different institutions without taking into
