Athabasca is Canada's open university. The university's Centre for Learning Accreditation, which has an international reputation for portfolio-based RPL, changed their focus from paper to electronic portfolios in 2011, with the adoption of the open source Mahara eportfolio.
Although they still accept paper portfolios, over 90% of portfolio submissions are now electronic.
