I examine the role of teachers’ encouragement in improving student outcomes using a representative
sample of U.S. high school students. A range of outcomes have been used to study the impact of teachers’
encouragement: 11
th grade GPA, high school Math GPA, high school Science GPA, Math self-efficacy,
Science self-efficacy, and selectivity of the colleges that students enrolled in 2013. The main independent
variable of interest is a binary indicator built on the student observation - whether the student took math
and science in 11th grade because teachers encouraged them. Using restricted-access data from the High
School Longitudinal Study of 2009, sponsored by the U.S. Department of Education, I show that
teachers’ encouragement-driven math class enrollment in 11
th grade is associated with a 0.05 standard
deviation increase in high school math GPA. On the other hand, teachers’ encouragement-driven science
class enrollment in 11
th grade is associated with a 0.035 standard-deviation increase in high school
science GPA. Secondly, Teachers’ encouragement-driven science class enrollment in 11
th grade is
associated with a 0.05 standard-deviation increase in science class self-efficacy. Finally, using selectivity
classifications of enrolled colleges provided by the Integrated Postsecondary Education Data System
(IPEDS), I show that teachers’ encouragement-driven science class enrollment in 11
th grade increases the
probability of enrollment in “highly selective” colleges by 2.8%.
