Some Grade 4 educators have expressed feelings of ineptitude regarding the support of ESL (English Second Language) learners with limited English proficiency as they do not know how to support these learners effectively. Their litany emphasises ESL educators' need for supportive and preventive intervention. A story-based Language Enrichment Programme (SLEP) was compiled to suit the needs of educators teaching Grade 4 ESL learners with limited English proficiency. The programme was designed to maintain or improve the English proficiency of ESL learners. An intervention research method was followed to test the efficacy of SLEP. Forty teachers implemented SLEP over a six-week period. Thirty-nine teachers provided constructive feedback at the end of this period. Between 92% and 100% of the participants rated SLEP positively. Rural participants suggested some refinements to the programme. The overall conclusion was that SLEP makes a useful contribution to ESL practice.
