About 2000 Western Cape pupils fall pregnant in a year, it was reported on Thursday.
Of these, only around a third would go back to school and complete their education after giving birth, the Cape Times reported.
Provincial education department spokesman Paddy Attwell told the newspaper 2097 pupils fell pregnant in 2011, compared with 2108 pupils in 2010.
"Our Cape Winelands district reported the highest number of learner pregnancies in 2011, followed by Metropole East, and Eden and Central Karoo," he said.
The department had reportedly developed a policy to provide step-by-step guidelines on how principals and governing bodies should support these pupils, to ensure they stayed in school.
They were given access to counselling by social workers and psychologists.
Attwell told the newspaper the type of support given depended on the pupil's medical condition and stage of pregnancy. The aim of the policy was for pregnant pupils to finish matric.
