A BATTERY OF TESTS WAS DEVELOPED AND STANDARDIZED TO MEASURE MASTERY OF TWO BRAILLE CODES--THE GRADE 2 LITERARY CODE AND THE NEMETH CODE FOR MATHEMATICAL NOTATION. DESIGNATED AS THE "COLORADO BRAILLE BATTERY," THESE TESTS PROVIDED OBJECTIVE MEASUREMENT DATA REGARDING A STUDENT'S OVERALL DEVELOPMENT IN BRAILLE, AS WELL AS A MEANS OF ANALYZING SPECIFIC STRENGTHS AND WEAKNESSES IN BRAILLE SKILLS. THE BATTERY SHOULD FIND USE WITH BLIND CHILDREN AND ADULTS, WITH SIGHTED PERSONS REQUIRED TO HAVE KNOWLEDGE OF THE BRAILLE CODES, AND AS A RESEARCH TOOL. (JM)
