The education system in Pakistan is generally divided into six levels: preschool (for the age from 3 to 5 years), primary (grades one through five), middle (grades six through eight), high (grades nine and ten, leading to the Secondary School Certificate or SSC), intermediate (grades eleven and twelve, leading to a Higher Secondary School Certificate or HSSC), and university programs leading to undergraduate and graduate degrees.
The literacy rate ranges from 87% in Islamabad to 20% in the Kohlu District. Between 2000 and 2004, Pakistanis in the age group 55–64 had a literacy rate of almost 38%, those ages 45–54 had a literacy rate of nearly 46%, those 25–34 had a literacy rate of 57%, and those ages 15–24 had a literacy rate of 72%. Literacy rates vary regionally, particularly by sex. In tribal areas female literacy is 9.5%. While Azad Jammu & Kashmirhas a literacy rate of 74%. Moreover, English is fast spreading in Pakistan, with more than 92 million Pakistanis (49% of the population) having a command over the English language, which makes it one of the top English-speaking nations in the world. On top of that, Pakistan produces about 445,000 university graduates and 10,000 computer science graduates per year. Despite these statistics, Pakistan still has one of the highest illiteracy rates in the world and the second largest out of school population (5.1 million children) after Nigeria.
