In assessment, researchers have recognized the powerful influence of culture, therefore the clients' ecology (Bronfenbrenner, 1977; Neville and Mobley, 2001) and subjective should be considered. There is a dearth of assessment tools that are culture based and this research aimed to bridge the gap. The overriding purpose of this study was to construct a culture sensitive screening tool that would help identify students who are potentially gifted in a general classroom. Specifically, the study explored the Visayan conception of giftedness . It was framed in a constructionism perspective with the utilization of exploratory design. Phase One is a qualitative exploration of the conceptions of giftedness while the Second Phase is constructing and validating an instrument based on the conception of giftedness. Survey and focus group discussions were conducted in a school with selective admission policy for school year 2014-2015. Purposive sampling was utilized through the administration of Otis-Lennon School Ability Test (OLSAT). Those who where above average and superior were chosen as informants including their parents and teachers in the first phase of the study. There were 113 informants, 46 of whom were students, 23 were faculty and 44 parents. Theme analysis and KJ Method of Affinity Diagram were used as a data analysis. The construction and validation of instrument was the main purpose of the second phase. The 70-item instrument was subjected to phase validity and was administered to 285 students to test its validity and reliability. Factor Analysis and Cronbach alpha yielded an excellent result and the ten constructs of giftedness emerged from the factor analysis. These are perceived verbal ability volition, self-diagnostic function, perceived ability in science and math, task commitment, attentiveness, adaptability, resource management strategies, and self-efficacy. After a series of validation 60 items were retained. The results showed that the constructed instrument is valid and reliable. Hence, the Self-Rating Scale for Identifying Giftedness, that was developed is a culture sensitive assessment because this is based on the local conceptions of giftedness, that is, "giftedness according to the Visayans is an innate ability that is given by God. S/he is a self-regulated person who may have many abilities but has an exceptional ability in a specific field".
