Reading is very important to a pupil. The love of reading may only develop when the child has reading motivation and good reading habits. Family support and the home environment, too are great help in the childs reading development. Hence, this research study aimed to determine the level of the reading factors in reading in terms of reading motivation and reading habit, family support, and home environment among Grade V pupils to identify the level of the respondents reading performance as to PHIL-IRI result in the First Grading Period, the significant difference between internal factors affecting reading performance and the relationship of the external factors affecting reading performance among Grade V pupils.  It was conducted among the Grade 5 respondents ( n=321) of the five schools in South District. This study used a research-made questionnaire which was tested with a Cronbach result of 0.785. The study used the statistical treatment on the frequency, percentage, mean and standard deviation, and T-test. Findings show that the overall Level of Reading on Internal Factors was high level, and the External Factors resulted in a Very high level while the PHIL-IRI reading performance is on the Instructional level.
