Picture a classroom in rural Kenya. You have fifty students in grade 5 trying to learn how to read and write so they can reach their dreams. Because they have a dedicated teaching assistant, they have someone they can trust with their questions. Even though the student-teacher ratio in their school is 52:1, all their work is graded on time and each of them receives individual attention. They have someone who follows up when they are absent, when they have behaviour challenges and when they struggle with coursework.
In a world without PACE, classrooms like this one suffer. The promise of Education for All fades under the strain on the limited teaching resources.
