This paper considers the influence of e-tuition using an asynchronous written conferencing package, "FirstClass," upon retention and success rates for Masters-level courses in a distance learning programme as compared with similar courses that were supported in a traditional manner using face-to-face tuition. The paper investigates the common assumption that the use of e-tuition might negatively influence both retention and success rates by studying data gathered on UK Open University Masters courses in education. These data have allowed direct comparisons between e-tutored and face-to-face tutored courses to be made. The effect of linking assessment to participation in activities using "FirstClass" is also considered in this study. This research has revealed that e-tutoring using "FirstClass" appears to have no significant positive or negative influence on either retention or success on such courses. (Contains 2 tables.)
