Does it affect the relationship between "syllabus and materials" The quality of education in your school?
contains some ambiguity. Is the pronoun it meant to mean "The quality of education in your school"? If so, the answer is Yes. The quality of education in a school often influences the choice of many programs and materials. With lower standards of quality in the educational process, the choices that will be made as far as learning goals and the learning materials will also be below standards of excellence because less will be expected of students.
