The administrative data set refers to the source of information related to all official registers about schools, teachers and students. The data itself are collected for administrative purposes on a yearly basis. These data bases were not particularly designed to be a longitudinal panel but given their availability over the years we are able to construct our own SPD.
All available information is provided at national level and it is possible to be linked to each other by student ID (Mrun), school ID (RBD) and teacher ID. Within the administrative data set, we classify six data bases described below. Some of variables overlap across data bases, that is why we aggregate all of them in a unique list referring to the administrative data set variables. See Appendix 3.3, a description of the list of variables observed in the administrative data set and their availability through the period 2002-2013.
Enrolment data base
This is a yearly register of all the students enrolled in the Chilean schools system. Every type of school has to provide the list of students officially enrolled to the Ministry of Education by the end of April (the academic year regularly starts the first week of March and finishes in middle December).
Performance data base
The Study Centre of Mineduc manages a yearly data base using the final academic report submitted by all schools at the end of the academic year. Here, it is possible to recover the final academic status, the grade point average (GPA) and school attendance.6
Given the information contained in this Performance DB, it is more likely to find duplicated registers per student-year than in the Enrolment DB (due to possible changes in GPA or final status). The evidence also confirms this con- jecture, the rate of observations with duplicated schools per student is higher if we use the Performance DB, than the Enrolment DB when we use them as the reference data base to construct the SPD.
School marks data base
This is the official register of the whole aggregated student’s school marks.7 Every
student has as many observations as school subjects taught per year. We recover the registers related to Language and Mathematics subjects (the rest of the sub- jects are available as well). It is also possible to match these records with the teacher’s subject area reported in the teachers data set.
6The grade point average (GPA) correspond to the average mark of all final subjects’ mark
by the end of the academic year.
7All schools report the final mark for every student enrolled. The final mark correspond to
School directory data base
In parallel to the individual student register, the Mineduc has also constructed a yearly register of all schools in the Chilean education system. Most of the variables contained in this school register data base are already included in the Enrolment DB or Performance DB. What is exclusively in the School directory DB is the school phone number and address.
Teachers data base
The teacher records are organised in yearly files where each observation identifies a teacher ID with the subject and the specific classroom taught. This means, it is very common to find multiple observations per teacher ID. For example, general teachers have different registers for every subject (Language, Maths, Science, etc) taught in the same class. On the other hand, the majority of teachers from 5th grade onwards are subject specialist (SS) teachers. We call SS teachers to those teachers who teach a specific subject to more than one class in the same grade, or in multiple grades and schools.
For matching teacher IDs to the SPD we have to separate the teachers data base in two; Language teachers and Maths teachers. Then, we merge those data bases independently to a specific cohort (using school ID, grade, and class letter). We identify a SS teacher when for the same classroom we observe to different teacher IDs associated, one for Language and another for Maths.
School staff data base
This data set identifies all teachers and managerial staff with a contractual re- lationship in a school. Every employee has associated a unique and masked ID provided by the Mineduc, which in case of teachers is the same as the one used in the Teachers DB described above.
The observations are organised by job positions, identifying the role of the employee in the school. It is possible to find more than one observation per individual as one teacher could have more than one role in the same or a different school. However, the teacher’s ID key variable allow us to enrich the SPD with some observable teacher characteristics obtained from this data base.
Apart from having available individual characteristics such as; gender, date of birth and the experience in the education system, the fact we have access to the role of the individual in the school, allow us to identify principals and some of their characteristics as well.
