... eliability level of 0.908. The data analyzed using descriptive analysis and inference analysis. Vygotsky's Constructivist Theory underlying this study and the model of co-teaching by Friend and Cook were adapted. The findings showed that the implementation level of the co-teaching components was at a moderate level (Mean = 3.90, SD = 0.42), and there was no difference between teacher categories towards the implementation of the co-teaching components with t (38) = -0.387, p= 0.701 (p> 0.05). Those findings indicated that the co-teaching components' implementation level could be further enhanced through the teachers' training and professional development. The initiatives can improve the teacher's understanding of the co-teaching components for more effective implementation. In addition, the combination of field expertise and an equivalent commitment from mainstream and special education teachers will positively impact the teaching and learning process in the inclusive classroom. In conclusion, the tremendous implementation of co-teaching components can improve teaching quality in inclusive education classes and fulfill the special education students' needs and access to education.
