This study focused on 11 teachers involved in the Project for the Implementation of Remedial Instruction (PIORI), utilizing document analysis and in-depth interviews to explore their perceptions of remedial instruction and the challenges and issues they faced during the implementation of remedial instruction. It also analyzed the factors that influenced their willingness to work. Findings revealed that challenges arose from interactions with students and were influenced by project regulations, as well as student and parent attitudes and teachers' backgrounds. Teachers were categorized into three types based on willingness and abilities, with tailored administrative recommendations: First, for willing but less skilled teachers, professional development opportunities were provided, and teaching pressure was reduced. Second, incentives were enhanced, and barriers were removed for skilled but unmotivated teachers. Finally, for those with both willingness and ability, support focused on managing stress, maintaining enthusiasm, and improving skills. These recommendations guided educational authorities and school administrations in managing remedial instruction teachers effectively.
