The Alternative Learning System (ALS) is a free education program run by the Department of Education that provides an alternative to formal schooling for out-of-school youth and adults. It aims to promote universal access to basic education and improve socioeconomic outcomes. ALS offers various programs including literacy programs, mobile teaching, and an accreditation and equivalency program. It targets learners like drop-outs, unemployed adults, and cultural minorities. While ALS expands educational access, it faces challenges like lack of funds, developing suitable curriculum, teacher attitudes, security issues in remote areas, and coordination with communities.
