Task: Question Generation
Input (English): Passage: Caversham has no secondary schools, although it does contain two primary schools and a special needs school. Caversham Primary School, at the corner of South Road and Surrey Street, has been at its present site since 1921. The school dates back to the early 1860s, and has a current enrollment of around 80 pupils. The school's two-storey 1920s brick buildings were pulled down and replaced in 1961, because of their structural unsoundness. The school's main gate – the only surviving remnant of the earlier structure – is the suburb's war memorial.College Street School, south of South Road's retail area, was built on an earlier site of Caversham Primary School. It was officially part of Caversham Primary School until 1959, when it was declared a separate institution, and now has about 250 pupils. A third school, the Sara Cohen School in Rutherford Street, was established in 1926. This school caters for special needs pupils from primary school age through adulthood. The school was named for the late wife of Mark Cohen, city councillor, campaigner for women's rights, and editor of the Evening Star newspaper from 1893 to 1920. In 1889, Mark Cohen was a major figure behind the founding of New Zealand's first kindergarten.There are kindergartens and child-care centres in both Rutherford Street (by Kew Park) and South Road (to the east of the main retail area), and there are numerous pre-school facilities and further primary schools in the suburbs of Forbury and Saint Clair, immediately to the south of Caversham. The nearest secondary schools are the single-sex schools of Queen's High School and King's High School, located alongside each other close to the boundary between Saint Clair and South Dunedin, 1 kilometre (0.62 mi) to the south.
Output (English): What is the name of the separate institution that now has about 250 pupils?
