   Does class size affect reading scores of students?

   angrist_using_maimonides (agent)

   The dataset contains data on 5th graders enrolled in Israeli public elementary schools. The schools had imposed an upper limit on the class size of 40. In case the class size exceeds 40 students, another class is set up. To ensure balance across multiple classes of the same grade, students are split roughly evenly. In addition to including information about the school and the class size, the dataset also includes data on student performance in verbal (Hebrew reading) and mathematics tests. Variables include: schlcode: School identifier code towncode: Town identifier code townname: Town name townid: Town identifier (same as towncode) popcode: Population/administrative code used for linkage grade: Grade level (e.g., 3, 4, 5) classid: Class identifier within school and grade c_size: Total number of 5th graders in the school classize: Total number of students in each class, post-splitting if enrollment is greater than 40 c_boys: Number of boys in 5th grade c_girls: Number of girls in 5th grade c_numcl: Total number of classes in the school c_type: Total number of classes in the 5th grade cohsize: Total number of students in the 5th grade (same as c_size) classct: Count of classes in the 5th grade (same as c_num5rd) c_num5rd: Total number of classes in the 5th grade (same as c_type) mrkgrm5: Average reading (verbal) score for grade 5 ngrm5: Number of fifth-grade reading test takers nmth5: Number of fifth-grade math test takers mathsize: Number of students who took the math test in the class avgmath: Average composite math score in the class (1-100 scale) passmath: Share of students passing the math test in the class verbsize: Number of students who took the reading test in the class avgverb: Average composite reading (verbal) score in the class (1-100 scale) passverb: Share of students passing the reading (verbal) test in the class studchk: Data quality/student consistency check indicator (1 = no missing data) impute: Indicator that class-level averages were imputed from school totals tip_a: Percent of disadvantaged students (same as tip_s) tip_s: Percent of disadvantaged students tipuach: Percent of disadvantaged students (same as tip_s)
