This study examined whether or not students using a career ePortfolio, including a matrix for identifying and reflecting on transferrable skills, enabled them to rate their skills more confidently and positively after a simulated (mock) job interview. Three groups were studied: those completing the skills matrix in the ePortfolio; those using the ePortfolio but not the skills matrix; and those not using the ePortfolio. Results of a one-way ANOVA indicated no significant score differences among groups on a self-reported skill survey. However, other findings pertained to difficulties in conducting research on the effectiveness of online career ePortfolios and suggestions for correcting such problems in the future.
