NZCER has been contracted to provide data analysis and professional advice services to the Ministry of Education (MOE) in relation to student profiles using the English Language Learning Progressions (ELLP), 2008. The services will include the continued analysis of a range of English language learners’ patterns of progress as they acquire proficiency in English language based on analysis already carried out in November and December 2009. The data for this purpose is referred to as ‘Cohort A data’. Also we are attempting to demonstrate the relationship between ESOL/AF (ESOL Assessment Funding) scores and the stages of ELLP across different age levels, and the relationship between the Reading and Writing Standards for years 1–8 years and the ELLP stages. This data is referred to as ‘Cohort B data’.
