Around 100 learners from Otjiwarongo Secondary School were sent home for allegedly failing to hand in raffle tickets.
Some of the parents of the affected learners criticiced the school management for the decision, describing it a way of denying them a right to education.
The parents said they did not understand why the pupils had to be sent home because of raffles, which do not form part of the curriculum.
Approached for comment, the Principal, Rina Goldberg, refuted the allegations that learners were sent home.
She claimed that the school handed out raffles to the learners voluntarily to sell, to raise funds in order to buy benches and tables for the school.
Goldberg said the raffles, considered to be the last fundraising exercise, were handed out to learners in May and they were due last week Friday.
She said as the school needs to reconcile the forms and money collected, learners were asked to go home or either ask their parents to bring the forms back, because the draw is due tomorrow (tue).
Goldberg said all efforts to raise funds are aimed at making it better for the children and parents are expected to promote the project.
