This paper describes the development of an electronic portfolio retrieval system “PRIUM” (Portfolio Retrieval for Investigating Useful Material) which reflects keyword similarity, and assessment of its retrieving efficiency. 40 elementary school students used PRIUM, and 40 elementary school students used a full text retrieval system during their Information Communication Technology (ICT) education class. The findings are that elementary school students who used PRIUM could find electronic portfolios they wanted quickly, because PRIUM lessens the need for seeing electronic portfolios they didn't want. In addition, it is clear that electronic portfolios which were made by prior students provide students with useful information even when such electronic portfolios are provided as teaching materials without relying on retrieval systems.
