The Universtiy of Pretoria has been using anelectronic assessment system since 1991 and a learningmanagement system (LMS) since 1998. Both systemsrequired urgent upgrading. In 2003 a further need arose inthe Faculty of Health Sciences, for an electronic portfoliosystem. The Department for Education Innovation (EI) hasthus implemented three new systems during the past threeyears: a new electronic assessment system, an upgradedLMS, and an electronic portfolio system. This paperanalyzes the advantages and challenges experienced in eachof the three different implementation models adopted.Recommendations are suggested, not as guidelines forinformation technology specialists, but rather for otherindividuals who are responsible for, or may consideracquiring, a new e-learning system.
