The 35-minute assessment includes eight different mental tasks presented like puzzles and games. The tasks provide a snapshot of primary cognitive skills, including auditory processing and word attack skills that serve as the foundation for reading.  \nHistory of the Test  \nThe first iteration of the test was developed in 2002 by pediatric behavioral optometrist, Dr. Ken Gibson as a screening assessment for his clinician-delivered cognitive training program. To establish a baseline of cognitive skill functioning in his patients, Gibson used a variety of different commercial tests. Desiring a single tool that could provide multiple measures, he designed the Gibson Cognitive Test Battery which has been administered more than 90,000 times since then. In 2014, his team began the process of collecting updated norms for the original test, culminating in a complete normative update in 2020 along with an updated look, automated scoring system, and a new name, the Gibson Assessment of Cognitive Skills (GACS). Note: In 2006, Gibson created a digital test called the Gibson Test of Cognitive Skills and a revised Version 2 in 2014. About 50% of the digital tests items are found on the GACS.  \n\n| Theoretical Foundation\u003Cbr>The test framework for The Gibson Assessment of Cognitive Skills (GACS) was guided by the CattellHorn-Carroll (CHC) model of intelligence, and the measurement of broad CHC factors (see Schneider & McGrew, 2018): fluid reasoning (Gf), auditory and visual working memory (Gwm), processing speed (Gs), visual processing (Gv), auditory processing (Ga), and reading and writing (Grw) . The ever-evolving CHC model of intelligence serves as the basis of Gibson’s Learning Model, a graphical depiction of how we think and learn. (See Figure 1.)\u003Cbr>Figure 1. Gibson’s Learning Model |\n| --- |\n| |\n| The Learning Model is independently recognized as an influential guide in the development of auditory and visual processing interventions (Press, 2012), and has been featured in our own peer-reviewed cognition research studies (Gibson, Carpenter, Moore, & Mitchell, 2015; Carpenter, Ledbetter, & Moore, 2016) . As demonstrated in Figure 1, there is substantial overlap between the two models of learning and cognition which is supported in the concurrent validation study outlined later in this manual comparing\u003Cbr>GACS to other CHC-based assessments. |\n\n\n| Uniqueness of the Test\u003Cbr>Given the number of cognitive tests saturating the market, it is important to highlight some critical differences between the Gibson Assessment and other cognitive assessments. First, as of this publication, the Gibson Assessment is currently the only cognitive assessment tool that measures four aspects of auditory processing and Word Attack skills in its core battery. Auditory processing skills are key components of the CHC model of intell","cbCaia3NX6v70y9N","https://ap.wps.com/l/cbCaia3NX6v70y9N","pdf",1225638,"English","# TABLE OF CONTENTS\n## Part I.
