According to the Universities Australia productivity paper, high student:staff ratios have a negative effect on retention. The citation for this claim is to a 2001 American academic journal article. But what does the local evidence suggest?
The figure below shows the student:staff ratios reported by Universities Australia and the attrition data reported by DEEWR for domestic commencing students (so retention is 100% minus the attrition rate).
Now there are problems with both sets of numbers. Actual teaching capacity is understated and actual attrition is overstated because of problems with the way the data is collected. But I don’t think those problems can explain away the trend evident in the figure. If the UA hypothesis was correct for Australia, student:staff ratios and attrition should be positively correlated: if SSRs go up, so should attrition. Instead, they are negatively correlated: as SSRs have gone up, attrition has gone down.Read More »
