São Tomé and Príncipe's system is pretty damn good, i found this the other day:~
Education in São Tomé and Príncipe is compulsory for four years. Primary school enrollment and attendance rates were unavailable for São Tomé and Principe as of 2001. The educational system has a shortage of classrooms, insufficiently trained and underpaid teachers, inadequate textbooks and materials, high rates of repetition, poor educational planning and management, and a lack of community involvement in school management. Domestic financing of the school system is lacking, leaving the system highly dependent on foreign financing.
