摘要:AbstractThe relationship between socio-economic status (SES) and student achievement is well documented and indicates that students from more advantaged backgrounds perform better at school. Numerous international and national studies have reported a significant association between students’ socioeconomic status and their achievement at school. This study aims to examine how the students’ Turkish achievement is associated with their own socioeconomic status. The study is a descriptive survey. Data were collected via an assessment test conducted by Altındağ Counseling and Research Center (ACRS) and the questionnaire the students answered after the test. The aim of the assessment test is to evaluate the students’ performance and their literacy skills in Turkish Language Class. The assessment instruments were developed by ACRS. The target population of the study consists of 4th, 5th, 6th, 7th and 8th grades at primary schools around Altındağ district in Ankara. 23036 students participated in the survey. The findings of the study are as follow: the association between students’ socio-economic status and the performance in the Turkish achievement test is statistically significant and positive (r=.20 p=.000). The association is significant (r=.13) at 4th grade and (r=.26) at 8th grade. Education level of the father is closely associated with the performance.
