　　Eighteen people in central Kenya are taking thecountry's secondary education test, called the KCSE.Even under normal conditions, this examination canmake a student nervous. But these 18 students mayfeel especially fearful. They are serving sentences in a top-security prison. And if they do wellon the test, they might get to leave the prison.

　　During the test the inmates sit at school desks at Naivasha Prison. These prisoners have writingtools and plastic devices used in mathematics. The classroom looks like any other except thatthe students are wearing prison uniforms.

　　David Noah Okwemba has just finished the examination for history and biology. He says hewants people to know that the prisoners are no longer criminals. Instead, he says they arestudents.

　　Prisoners who perform well can have their sentences amended. They may be released early togo to university or find employment.

　　Patrick Mwenda is head officer at Naivasha prison. He says Naivasha works with the high courtsto consider the cases of prisoners who get high marks.

　　Mr. Mwenda says nine prisoners have been released since 2008 as a result of their schoolingand tests. So far, the releases have gone only to prisoners sentenced to short terms.

　　Only one other possibility for freedom exists for those facing life in prison and those who haveused up all their legal appeals. Kenya's Power of Mercy committee advises about pardons forprisoners. Officials set up the committee in 2011.

　　Mr. Mwenda admits the difficulties of getting a pardon. But he says the prison urges studentswith longer sentences to build skills. He says doing this would help them have a good record toshow the committee.

　　Inmate Prince Winsor Mosii does not approve of the whole system.

　　"The Power of Mercy is not actually helpful. It is there, but it is not helping in setting us atliberty (freeing us), even if you have performed."

　　Prince Winsor Mosii took his KCSE exam last year. But he says he does not see much reason toget an education if he is to remain in prison.

　　"It is of no good to get or to acquire something of great value, skills, and not put it intoaction."

　　More than half of the 3,000 inmates at the Naivasha prison are involved in the school program.The inmates themselves choose the subjects and decide the content of the studies.
