The Reading Recovery programme has been a key early literacy intervention in many international contexts for over two decades. As a consequence, there have been numerous investigations into its efficacy for short-term gains, but only a few on long-term sustainability. This study examines the progress of 95 Year 4-6 students from seven schools in the rural hinterland of New Zealand. Standardised data were collected from students who had been successfully discontinued from Reading Recovery two to four years previously and compared them with mean performance from the same school populations. Results showed that only Year 6 students obtained the mean scores which placed them within the national average range. Our results also showed that whilst almost half of the ex-Reading Recovery students we studied, fell within the average band, 45% were classified as well below average.
