MANILA: The Department of Education (DepEd) said Friday it has begun investigating the alleged illegal sale of "Catch-up Fridays" and other school activity materials. Catch-up Friday is a learning mechanism which aims to strengthen learners' capacity in reading, writing, critical thinking, and analysis, among others, as part of the department's learning recovery efforts. In a statement, the DepEd said some school personnel were reportedly requiring learners to buy booklets and workbooks. 'DepEd has already commenced an investigation on the matter. Any individual found guilty of such (a) scheme shall face appropriate administrative sanctions,' the DepEd said. The DepEd said these materials are free, urging parents to be vigilant against such schemes. 'The Department reiterates that such acts are strictly prohibited. Catch-Up Fridays and other school activities must not involve out-of-pocket costs,' it said. 'Parents and learners are reminded not to accommodate and patronize such unauthorized transactions ,' it added. Victims or concerned individuals, meanwhile, may directly send their complaints to the Office of the Secretary via email at osec@deped.gov.ph. ( Source: Philippines News Agency
