Measuring client satisfaction with public education I: meeting competing demands in establishing state-wide...

By its very nature, a large-scale evaluation of client satisfaction with public education using a quantitative approach, places almost impossibly competing demands on the research methodology. This paper reports on the use of a suite of Rasch measurement techniques to meet the competing demands in establishing state-wide benchmarks relating to the School Opinion Survey carried out over 1200 government schools in one state of Australia. Although the evaluation had to establish system-wide representative parent and student benchmarks, meaningful quantitative estimates of client satisfaction had to be provided at the smallest public schools. The final 20-item School Opinion Survey Parent and Student Forms were designed following feedback from the administration of trial forms. Instrument development was monitored by the results of Rasch modeling. The Rasch modeling property of specific objectivity was empirically verified when calculation of identical benchmark estimates resulted from the construction of simulated population proportional samples using sample:population size weightings.
