This quantitative study used cross-sectional survey method by distributing questionnaires to the respondents. The questionnaire was developed by the researchers to suit the unique environment of the "tahfiz" schools and has gone through the process of validity and reliability. Descriptive analysis showed that student attitude variable showed a high level of mean score (above 3.80), while for school climate variable, the finding was at moderate level (Mean=3.56, SD=0.530). As for curriculum variable, most students learnt the same main subjects as studied in government-aided primary schools, with addition to Quranic subject. However, no one learnt Computer Education subject.
