This action research focused on the challenges of assessing student in printed modular distance learning. The main challenges identified by the teacher in assessment were dishonesty in answering the modules and commitment of students to submit output. To be able to minimize this, preparing varied authentic assessment might be the best approach. It may be good if the teacher can present activities that will fit the students abilities so that they are encouraged to give their own answers. The researcher used one rubric appropriate in all types of authentic assessment. The researcher utilized one-group pretest and posttest research design. Forty (40) Grade 10 students were purposively selected by the researcher to be the respondents of the study. The students were given a hard copy of the work text that contains seven (7) activities focusing on the topics covered in the 3rd quarter. A paired T test was used to determine whether there is a significant difference between the pretest and posttest scores of the students. Result of the study showed that there is a significant difference in the problem-solving skills of the students after using AHA (At-Home Assessment) Approach. The researcher recommended that AHA (At-Home Assessment) Approach be used as an instructional intervention in improving the performance skills among the Grade 10 students.
