This paper reports on literature related to the assessment of barriers to educational technology assessment. It surveys the development of technology acceptance models from social cognitive theory and innovation diffusion theory through to a unified theory that considers performance expectancy, effort expectancy, and social influence. Because risk is a significant factor in technology assessment, this paper outlines risk assessment processes, beginning with the Fine-Kinney method through to derivation of a risk matrix. Finally, it considers factors related to the validation of technology acceptance survey assessments. [For the full proceedings, see ED665357.]
