{"abstract":"One of the most ultimate goals of every math teacher and the school is to improve the level of proficiency and academic achievement of low performing students in Mathematics. This study focused mainly on the proficiency and academic achievement of Grade 7 students in Mathematics. The research design used is Quantitative Descriptive Comparative and Correlational technique. In 96 sample respondents, 48 were males and 48 females. Stratified random sampling was employed in the selection of respondents per strata. Based on the results, the level of proficiency of the students was low/below standard and the level of academic achievement of the students was satisfactory. It showed that the mean difference of the proficiency and academic performance of students when grouped according to sex was not significant at 0.05 alpha level, therefore the hypothesis is accepted. However, there existed a significant relationship between the proficiency and academic achievement of students in Mathematics. It revealed that the null hypothesis was rejected. It is concluded that the proficiency of Grade 7 students had a great impact on the academic achievement in Mathematics. Based on the results of the study, a Development Program in Mathematics was made to improve the proficiency and academic achievement of students.","abstract_source":"original","authors":["Riza Berrame"],"date":"2024-04-30","doi":"10.5281/zenodo.11099553","id":2866,"issue":5,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"9e2041a2d8172108d44b6dd2c88000a57e132175cb79ea12c974ad2d130ed985","schema":"scimatic-article/1","title":"Proficiency and Academic Achievement of Grade 7 Students in Mathematics","volume":19}
