The purpose of this study was to develop an achievement test suitable for eighth grade industrial arts, in the Province of British Columbia. The test was designed to conform to the limitations established in the curriculum bulletin, Industrial Arts 8, authorized in 1962. Norms were to be developed from the data resulting from the administration of the test in final form. On the basis of the results the test was to be examined for reliability and validity of the questions. The review of literature helped establish the need for such a test, and suggested the form of some of the test items. It was of little assistance in the actual construction of standardized tests in industrial arts. The test items were developed with consideration to aims, outcomes, course content, as defined in the curriculum bulletin. They were also developed with references considered suitable for this grade level. Questions were constructed in each of the four areas studied in eighth grade. These areas are woodwork, metalwork, electricity, and drafting. The trial set of questions were then submitted to a jury, consisting of personnel engaged in teacher education, and supervision, teachers of industrial arts, and student teachers of industrial arts. On the basis of the criticism received the questions were revised. A test, consisting of 240 questions, 60 in each area, woodwork, metalwork, electricity, and drafting was prepared, This test was administered to 96 grade eight students in June, 1963. These questions were revised using both subjective analysis as well as objective item analysis. The subjective analysis was undertaken by a graduate class of experienced industrial arts teachers during the summer of 1963. The revised test contains 50 questions in each section. The ten poorest questions in each section were eliminated, and the remaining questions improved wherever possible. The test in final form was completed by 684 eighth grade students in 12 British Columbia schools in June, 1964. The mean for the test in final form was found to be 84.71. The means for the individual sections of the test were as follows: woodwork 26.06, metalwork 24.87, electricity 22.64, drafting 12.97. The standard deviation is 19.73, 71.48% of all scores lie between plus one standard deviation, and minus one standard deviation. The reliability coefficient, calculated using the analysis of variance technique, is .89. An item analysis of all questions has been made and is discussed and full information presented.
