This evaluation included 81 percent of RTM clusters (that is, 43 of the 53 RTM). ERO selected RTM rohe to reflect, where possible, the national characteristics of the RTM service.
The following characteristics were considered:
RTM attending the national NARTAM Hui a Tau NARTAM Hui a Tau27, held in Palmerston North, March 2008. identified further characteristics for ERO to consider when making its final sample decisions. Aspects such as increasing the coverage of RTM sampled in the Central North Island region, to reflect the high number of immersion education options available, particularly in Waikato, Waiariki and Tuwharetoa schools and kura.
ERO’s final selected-service sample was broadly representative of these characteristics. Central North Island sample numbers were successfully increased. Specific information, from all RTM ‘rohe’, was considered in this evaluation.
