ABSTRACT: An ex post facto quantitative study with a qualitative aspect was used to determine relationships among Theory of Test Anxiety constructs and their influences on test performance of third-grade students (Sarason, Davidson, Lighthall, Waite, & Ruebush, 1960). The study was conducted in three elementary schools located in a school district in Northwest Florida. The following four instruments were used in the study: (a) Children's Test Anxiety Scale (CTAS; Wren, 2000), (b) Florida Comprehensive Assessment Test (FCAT; Florida Department of Education, 2011b), (c) Parent Reflection Form, and (d) Teacher's Reflection Form. Related literature connected Wren's (2000) subscales (thoughts, overwhelming tendencies, and autonomic reactions) with Sarason et al. (1960) constructs (anxiety, anxious reaction, need achievement, and achievement motivation).
