Part-time employment during high school has grown dramatically. High s
chool students are twice as likely to be working part-time as they wer
e in 1950. Despite the fact that many adolescents work between the age
s of 12 and 17, little empirical evidence exists about the impact of p
art-time employment on academic performance, In the present research,
the nationally representative sample of 10th graders, the First Follow
-Up of the National Educational Longitudinal Study of 1988 (NELS-88),
was used to examine the effects of part-time work during the school ye
ar on academic achievement, as measured by the standardized achievemen
t scores and high school grades earned in 4 subject areas: English, ma
thematics, science, and social studies. The findings of the study poin
t to a small negative effect of employment on both measures of achieve
ment when socioeconomic status, gender, and previous achievement were
controlled. The study helps to illuminate an important question and ha
s implications for parents, educators, and counselors.
