The aim is to test some broad ability of the newly developed tests, namely processing speed ability, consisting of three narrow abilities. In accordance with Cattel Horn Carrol theory, processing speed ability is one of the broad abilities that contribute in shaping general intelligence. There are three narrow abilities of processing speed ability, namely perceptual speed, number facility and rate of test taking. These abilities were studied through 299 items and were piloted on 135 subjects. Through confirmatory factor analysis using the JASP 0.9 program, the model was found as a good fit (χ² = 0.341, p=0.559 (greater than 0.05), df =1, RMSEA = 0.000 (90% CI [0.000 - 0.0191], and those three factors (perceptual speed, number facility and rate of test taking) were consistent with factors measured in processing speed ability tests. Based on the model accuracy index, it shows that the proposed model is capable of describing the narrow ability of processing speed ability. 1 INTRODUCTION Cognitive ability has become an important subject in psychology because it shows one of the individual differences of concern by psychologists. Cognitive ability can take the form of intellectual potential, logical thinking ability, comprehension, analytical ability, numerical ability, verbal ability and intelligence etc. Scientists consider that intelligence plays an important role in determining human behavior. Intelligence is considered capable of predicting individual success in careers (Gottfredson, 2009; Kaufman et al., 2012), study (Lohman and Gambrell, 2012; Lohman et al., 2008; Naglieri et al., 2003; Vanderwood et al., 2001) and survival (Vanderwood et al., 2001). Based on its very important role, assessing (i.e. knowing or measuring) the capacity of intelligence in a person is important. Assessing someone's intelligence is related to assessment activities that ultimately relate to intelligence tests. A psychological assessment activity is an attempt to evaluate the individual who is facing the problem; this activity explains that the information obtained from the assessment that can be used to solve the problem (Marnat, 2003). The assessment will be related to the measurement activity which is a systematic procedure for observing someone's behavior and describing it with the help of a numerical scale or categorization system. Meanwhile, the test is one of the means of collecting data on measurement activities. The test activity is an objective and standard measurement of a behavioral sample (Anastasi and Urbina, 1997). Tests play an important role in psychological decision-making regarding the fate of individuals, groups and the wider community. However, decision-making becomes less precise when the available data is less accurate. Finally, the accuracy of the data indicates the quality of assessment activities that are influenced by the quality of a test kit. While the quality of a test tool can be seen from the evaluation that should be done before using the test tool. One of the evaluations that can be done is on the validity aspects of the test. This article discusses the validity of the Speed Processing Ability test as part of a common intelligence developed based on the Cattel Horn Carrol theory (CHC theory). The Cattel Horn Carrol theory is the theory of intelligence which is the integration of Gf-Gc theory 156 Andriani, F., Hadi, C., Purwono, U. and Sulasmi, S.
