The contemporary study is an effort made by the researchers to measure the Mathematics Anxiety of students of Secondary School of Jammu Municipality in relation to their Gender, Type of School and Achievements. It looks for variations in anxiety levels between children attending government and private schools, as well as between boys and girls. The project also aims to investigate the relationship between mathematics achievement and anxiety, providing information on how anxiety impacts mathematical academic performance. The researchers selected the 434 class 10th students studying in the various government and private schools of Jammu Municipality as a sample by using simple random sampling. Out of which 209 were girls and 225 were boys. Investigators employed Mathematics Anxiety Self- Test (MAST) constructed by P. Don Bosco and Dr. V.D Swami Nathan in 2021 as a tool for data collection. The scale consists of 20 items which obtained responses on five points. According to the study, there is a negative correlation between secondary school pupils’ achievement and their worry about mathematics. Additionally, study demonstrated that there was no discernible difference in the level of mathematics anxiety between secondary school pupils attending government and private institutions. Beside this, the study also proved that the boys and girls of secondary schools were found to reveal insignificant differences in their mathematics anxiety.
