Data from Tennessee’s Project STAR study.
This data frame describes student participants in the Project
STAR (Student-Teacher Achievement Ratio) field experiment
conducted in Tennessee, USA beginning in the mid-1980s, as well
as an external control group consisting of the contemporaneous
cohort of students attending a matched sample of Tennessee
schools that did not participate in the STAR experiment.
Variables are as described in Project STAR data
documentation (see references), with the exception of the
three *_at_entry variables. These variables were reconstructed
as follows: grade_at_entry indicates the grade of student's
first participation, while school_at_entry and
cond_at_entry reflect the school ID and classroom type corresponding
to the student's grade at entry to the study. Additionally, read_yr1
and math_yr1 were added to capture the SAT scores specifically in the
year participants entered the study.
