With the overall increase of enrollment rates, there continues to be a large strain on the resources for education. UNICEF notes that without an increase on expenditures for education, the quality of education will continue to decrease. Early in the 2000s, the UNESCO International Bureau of Education found that the education system in Iraq had issues with standard-built school buildings, having enough teachers, implementing a standardized curricula, textbooks and technologies that are needed to help reach its educational goals. Teachers are important resources that are starting to become more and more strained with the rising number of students. Iraq Centre has a faster enrollment growth rate than teacher growth. Teachers begin to have to take in more and more students which can produce a bigger strain on the teacher and quality of education the children receive. Another large resource for education is libraries that can increase literacy and create a reading culture. However, this can only be improved through a restructuring of the education system.
