In 2006, the National Education Blueprint 2006–10 was released. The Blueprint set a number of goals, such as establishing a National Pre-School Curriculum, setting up 100 new classes for students with special needs, increasing the percentage of single-session schools to 90% for primary schools and 70% for secondary schools, and decreasing class sizes from 31 to 30 students in primary schools and from 32 to 30 in secondary schools by the year 2010. The Blueprint also provided a number of statistics concerning weaknesses in education. According to the Blueprint, 10% of primary schools and 1.4% of secondary schools do not have a 24-hour electricity supply, 20% and 3.4% respectively do not have a public water supply, and 78% and 42% are over 30 years old and require refurbishing. It was also stated that 4.4% of primary students and 0.8% of secondary students had not mastered the "3Ms" (reading, writing and arithmetic). The drop-out rate for secondary schools was given as 9.3% in urban areas and 16.7% in rural areas.
