D A T A B A S E F I L E S C H A P T E R 7 provided, including all Population 1 teachers. In some countries, however, a portion or even all of the students were taught mathematics and science by different teachers. Therefore, the IDSUBJCT variable was used to identify the appropriate teachers to include in background data tables in the international mathematics and science reports for Population 1. 7.2.1.5 Achievement Scores Student-Level Achievement Score Variables Variables representing students’ proficiency scores in mathematics and science are discussed in Chapter 6. These variables were used in the reporting of international achievement results in the international reports and are provided in the Population 1 and Population 2 Student Background files under the following variable names: AIMATSCR Population 1 International Mathematics Score AISCISCR Population 1 International Science Score BIMATSCR Population 2 International Mathematics Score BISCISCR Population 2 International Science Score The following additional achievement variables described in Chapter 6 are also provided in the Student Background files: ASMPV01 - ASMPV05 Population 1 - Mathematics Plausible Values (1-5) ASSPV01 - ASSPV05 Population 1 - Science Plausible Values (1-5) BSMPV01 - BSMPV05 Population 2 - Mathematics Plausible Values (1-5) BSSPV01 - BSSPV05 Population 2 - Science Plausible Values (1-5) AIMATEAP Population 1 - International Mathematics Score (EAP) AISCIEAP Population 1 - International Science Score (EAP) BIMATEAP Population 2 - International Mathematics Score (EAP) BISCIEAP Population 2 - International Science Score (EAP) ASMNRSC Population 1 - National Rasch Mathematics Score (ML) ASSNRSC Population 1 - National Rasch Science Score (ML) BSMNRSC Population 2 - National Rasch Mathematics Score (ML) BSSNRSC Population 2 - National Rasch Science Score (ML) ASMSCPT Population 1 - Number of Raw Score Points in Mathematics ASSSCPT Population 1 - Number of Raw Score Points in Science T I M S S D A T A B A S E U S E R G U I D E 7 - 7

These variables have prefixes of IL or IT. Some of the important linking and tracking variables are listed below. 3 Variables Included in the Student Background Files ITSEX Gender of each student ITBIRTHM Month of birth of each student ITBIRTHY Year of birth of each student ITDATEM Month of testing for each student ITDATEY Year of testing for each student 2 Survey Tracking forms are listings of students, teachers, or schools used for sampling and administration purposes. 3 Some additional linking and tracking variables included in the international background files but not listed above are indicated in the codebooks described in Section 7.3. 7 - 8 T I M S S D A T A B A S E U S E R G U I D E
