To support students’ progress in learning English, London International Academy has adopted the STEP program, developed for the Ontario Ministry of Education. The STEP program specifies learning criteria for students’ oral skills, and reading and writing abilities and enables teachers to provide specific descriptive feedback to students, enabling them to progress systematically through the ESL curriculum.
