Protocol: Delivery and Teacher Support as Moderators of Teaching at the Right Level Effects. A Systematic Review and Meta-Analysis

Protocol for a systematic review and meta-analysis of Teaching at the Right Level (TaRL) and closely related level-based remedial programmes in low- and middle-income countries. The review estimates the pooled effect on primary pupils' literacy and numeracy and tests whether implementer, ongoing teacher support, delivery format, region and outcome domain moderate effects. This protocol is deposited retrospectively: it records the plan drafted before the database searches and was made public after the review was completed. The review was not registered in advance. Section 10 lists every change between the initial plan and the completed review.
