A new book of standards for quality of tests has been published in Spanish, filling a gap on this field. The book includes 64 standards, comments, a companion questionnaire for self-evaluation and a planning schedule; with those tools a non-expert may understand the standards, and easily follow some procedures to design or to improve a test. The set of standards include these chapters: Organization of the project, Technical manual and planning of the test, Validity, Items and objectivity, Reliability, Test construction, Test scoring and interpretation of the results, Materials for the test, Application and logistics, Presentation of the results, Promotion and contracting. Following the standards' set, the self-evaluation questionnaire allows the responsible person of the test to identify what has been done, pending activities and show the elements to be included in the technical manual of the test. The questionnaire has a guide that specifies the standards to be fulfilled by a specific test, according to its purpose: from a teacher's made test up to an evaluation agency. After the questionnaire has been solved, the responsible of the test may look at the planning including at the end of the book. Once selected the standards to work on, and eliminating the rows corresponding to the standards not needed for the test, the remaining rows show the planning suggested for 6, 12 and 18 months. This suggested planning may be modified by the responsible of the test, but it provides a good foundation to start with the real planning. The standards and recommendations have been used to evaluate the quality of more than 60 objective tests developed in Latin American countries, with better results than the subjective procedures followed in the past with other standards or manuals.
