"This study is conducted to determine the predictors of the science performance of senior high school students under the science, technology engineering and mathematics (STEM) Strand during the pandemic. The respondents of the were the 83 senior high school students of Bais City National Science High School. The researcher utilized the descriptive-correlational method of research and used a validate questionnaire as data gathering instrument. For data treatment, the researcher applied the following statistical tools: percent, mean, weighted mean, Pearson Product Moment Correlation, and Spearman Tank Correlation Coefficient. The results indicated that the students' performance in science admission test, General Biology 1 and 2 , and General Chemistry 1 and 2, and General Physics 1 and 2 is in the outstanding level. The results also revealed a weak and inverse relationship between the students' performance in General Biology 1 and 2, and General Chemistry 1 and 2. A weak and positive relationship was also found between the students' performance in science admission test and their performance in General Physics 1 and 2. Furthermore, the results suggested that the students have high extent of perceptions of their self-concept, personality characteristics, interest, and motivation, and a somewhat high extent of perception of their achievement expectations. Lastly, it was found that the perceptions between male and female students differ in terms of self-concept and achievement expectations in favor of the male students. --Abstract
