This study examines the achievement levels of junior high school students in the coastal regions of Java, Indonesia, using Next Generation Science Standards (NGSS). It found significant differences in academic performance among students from Tegal, Pekalongan, Pati, and Demak, with students from lower economic backgrounds performing better than those from higher economic backgrounds (p=0.012). The results indicate that socio-economic factors and parental support significantly influence students' academic achievements in science education.
