This volume is the Spanish translation of Standards for Educational and Psychological Testing, 2014 edition. Developed jointly by the American Educational Research Association, American Psychological Association, and the National Council on Measurement in Education, Standards for Educational and Psychological Testing (Revised 2014) addresses professional and technical issues of test development and use in education, psychology, and employment. It includes changes in federal law and measurement trends affecting validity, testing individuals with disabilities or different linguistic backgrounds, and new types of tests, as well as new uses of existing tests. In the past 15 years, important developments have occurred in the field of testing, requiring significant revision to Standards. Five areas, in particular, receive attention in the 2014 revision: examining the accountability issues for the uses of tests in educational policy; broadening the concept of accessibility of tests for all examinees; representing more comprehensively the role of tests in the workplace; taking into account the expanding role of technology in testing; and improving the structure of the book for better communication of the standards
