| Description | The Hunter Science Aptitude Test (Lesser, Davis, & Nahemow, 1962) is used to identify science talent in gifted elementary school children. It consists of two forms: Form AX and Form BX, each containing 91 items. The test measures four aspects of science aptitude: (1) recalling scientific information, (2) assigning meaning to observations, (3) applying scientific principles for predictions, and (4) using the scientific method. Responses are scored on a scale of 0, 1, or 2, with total scores ranging from 0 to 182 for each form. The test was developed by selecting components of science aptitude and abilities appropriate for children aged 6-7 years. Reliability coefficients were low, but predictive validity was very high based on a sample of third-grade students. |
