Regarding the assessment of the respondents, parental involvement components such as Guiding, Communicating, Home Training and Attending Meeting/School Conference that affected the learner’s performance were assessed often by the parents.

Among the three, the financial aspect had the notable mean of 3.67 verbally interpreted as Often. There was no significant difference on the assessments of the two groups of respondents on the extent of parental involvement since the t-value did not exceed the 0.05 level of significance which failed to reject the null hypothesis.
