This is the first of two reports on existing measurement techniques for assessing characteristics of the home and educational environments and personal characteristics of children from birth to 9 years of age. In order to facilitate the use of currently available measures, tests have been categorized in terms of 10 broad areas and subcategorized in terms of the constructs they measure. The 10 areas of classification used are: (1) test batteries measuring many constructs; (2) measures of aptitude and/or intelligence; (3) measures of the ability to cope with cognitive demands; (4) measures of the ability to cope with personal-social demands; (5) family measures; (6) measures of language development; (7) measures of sensory-motor or physical skills or status; (8) measures of subject-matter achievement; (9) measures of teacher and or program; and (10) miscellaneous measures. As indicated above, each measure was further assigned to one or more construct areas depending upon test content. For example, the broad area "ability to cope with cognitive demands" includes tests measuring the following and other constructs: attention; attitude toward school; curiosity; memory; and reasoning. In separate sections of the report the methodology and general conclusions of the review are indicated. Titles of tests are listed by construct in Appendix A. Appendix B provides a guide to the different test listings. (Author/RH)
