A new follow-up study into students who'd gone through the Reading Recovery programme in the US has found that initial gains may not last.
The programme, developed in New Zealand in the 1970s, has been exported to a number of other countries including the US, where US$55m was spent in 2010 expanding the programme to over 80,000 first-graders.
An initial study led by Professor Henry May, director of the Center for Research in Education and Social Policy at the University of Delaware, found Reading Recovery had a positive impact on students' early reading achievement.
But newly-released findings into how students have fared two and three years later has found those put through the programme had test scores on state reading tests below those of children who hadn't gone through it.
Kathryn speaks with Professor May, and to Professor James Chapman of Massey University, who says it backs up research he's conducted into Reading Recovery here in New Zealand.
