An administrator's manual and two reading comprehension tests in Spanish and English for use in elementary grades are presented here. The Spanish reading comprehension test was developed, standardized, and normed in Mexico; the English reading comprehension test was translated from the Spanish test. The tests were designed to be used in the following ways: (1) to determine the level of Spanish achievement compared with Mexican norms; (2) as an evaluation instrument for bilingual education programs; (3) to measure progress of United States students who are studying Spanish; (4) to determine degrees of bilingualism by administering both English and Spanish versions at different times; (5) to measure and report Spanish reading comprehension skills of the students as well as information about English achievement; and (6) as a research tool. In addition to the above information, the manual covers the following topics: (1) the Mexican educational system; (2) suggestions for psychologists and educators; (3) test development; (4) interpretation of the scores; (5) general directions for administration as well as directions for administering both tests; (6) information on Spanish grade equivalents and percentile ranks; and (7) information about English norms, grade level equivalents and percentile ranks.
