Information literacy has been recognized as a critical skill by professional associations and regional accrediting bodies. Consequently, institutions are increasingly integrating information literacy instruction into the academic curriculum, in turn creating the need to assess instructional impact. However, information literacy is a relatively new concept and credible assessment tools are only now forthcoming. This paper summarizes several information literacy assessment tools recent to the market, including three instruments that measure cognitive knowledge of information literacy skills at the general education level, and a test that measures knowledge of information sources and structures pertinent to the field of education. Information literacy has roots in library instruction, and two techniques derived from bibliometrics, a library and information science research method, are also presented.
