This article presents the lighthouse literacy strategies model using the concentrated language encounter (CLE) approach that has been successfully replicated in many countries in different languages and cultures. A review of CLE research studies and the project implementation in Thailand showed highly significant results in students' literacy skill improvement. The theoretical bases were derived from the research on language education in Australia with aboriginal children. Through the implementation program in Thailand, three CLE models/stages in teaching language and a specific "train the trainers" program were developed at different levels of literacy skills. Four different types of CLE literacy programs that include formal, informal, special education, and ethnic groups were successfully implemented.
