The Whole School Approach promotes reading and writing through reading schemes and exercises, writing activities, visiting libraries, and other proceedings to reach the students’ interest and improve their learning holistically in reading and writing. The main purpose of the study was to determine the improvement of the reading and writing skills of the Grade 7 students of San Vicente National High School using the whole school approach. The pretest and posttest experimental group design was used in this study. The Philippine Informal Reading Inventory (Phil-IRI)- formula and given text with 80 words was used to identify the improvement of reading skills of Grade 7 students in terms of word recognition and comprehension. The result shows that the Grade 7 students were confused in recognizing words and frustrated in question analysis and comprehension. Thus, the majority of the students belonged to the frustration level in their reading skills. The whole school approach focused more on the students’ basic skills rather than on higher-order thinking skills. It was recommended that teachers need to focus and assess more on their reading skills. They must use a variety of strategies and approaches that draw the students’ interest in learning.
