The Effectiveness of Catholic Primary Schooling

Although extensive research has compared Catholic and public high schools, little is known about Catholic primary schools. Using unique
data for two cohorts of primary school students, I nd that Catholic schooling does not have a signicant effect on mathematics and reading
test scores. These ndings do not change when school level test scores from the rst-grade cohort are used to account for selection bias in the
fourth-grade cohort. In fourth grade, Catholic schooling is associated with marginally fewer student absences than is public schooling.
I. Introduction
Coleman, Hoffer, and Kilgore 1982 sparked a hotly contested, on- going debate by reporting that Catholic high school attendance is associated with
higher test scores. Much of this debate focuses on the ability to control for the non- random selection of students into Catholic high schools. Researchers usually use
instruments based on detailed location and religion variables under the assumption that these variables affect the availability of Catholic schooling but have no direct
effect on achievement or attainment. Using these instruments, recent research gener-

However, Ludwig 1997 nds that many of these instruments are not exogenous, and Altonji, Elder, and Taber 1999 nd that functional form assump-
tions, rather than instruments, provide much of the explanatory power in these models.
The small literature on Catholic primary schooling suffers from similar problems with selection bias. Sander 1996 nds a positive and signicant effect of eight
years of Catholic primary school attendance on tenth-grade test scores. However, he does not control for Catholic high schooling in these regressions, so it is impossible to
determine whether Catholic grade school attendance or Catholic high school atten- dance drives these effects.

It is also unclear whether identication in his selection bias models comes from the instruments or the functional form assumptions. National
Assessment of Educational Progress NAEP data include Catholic primary schools but contain little student and school demographic data. Therefore, Lee and Stewart
1989 and Jones 1997 are only able to control for a few student characteristics and are unable to control for selection bias or prior achievement. Nonetheless, both
papers nd that Catholic primary school students outperform public primary school students in NAEP tests.
In this paper, I utilize a unique microdata set, the Prospects study of the Title 1 program, in order to analyze the effect of Catholic primary schools on test scores,
classroom behavior, and attendance. Because each Prospects school includes test score data for students in rst and fourth grade, I use the test scores from the students
in the rst-grade cohort as controls for selection bias for the students in the fourth- grade cohort under the assumption that ability and out-of-school factors have more
inuence than in-school factors in test scores for rst-grade students.
Using a value-added specication, I nd insignicant but generally positive effects of Catholic schooling on 1993 mathematics and reading test scores for students in
either cohort. Catholic schooling has no effect on classroom behavior. For the fourth- grade cohort, Catholic schooling is associated with a modest decrease in student
absences of less than one day per year. At the same time, Catholic school teachers are more likely than public school teachers to report that excessive absenteeism is
a problem.
