The Paul Blommers Measurement Resources Library provides resources and services to support the teaching and research needs of faculty, staff, and students of the University of Iowa, primarily serving the College of Education. The Blommers Library collection includes books, journals, research reports, and reference materials related to educational and psychological measurement, testing, assessment, and evaluation as well as an extensive collection of published and unpublished tests. The library is not affiliated with the University of Iowa library system, and is supported with non-state funding from the Iowa Measurement Research Foundation.
Be sure to use Blommers Catalog to search tests and collections.
The APA Science Directorate answers hundreds of calls and emails each year from persons trying to locate the right test or find more information about psychological tests. APA neither sells nor endorses testing instruments, but it does provide guidance in using available resources to find psychological tests.
