X-BASS – Cross-Battery Assessment Software System


Cross-Battery Assessment Software System offers School Psychologists and other assessment professionals a time-saving, efficient, expert method for interpreting and presenting findings based on the methods and principles of cross-battery assessment. X-BASS allows users to enter specific test data and information and have it analyzed. Preprogrammed formulas take the data entered and apply cross-battery assessment principles to conduct the analyses. The software then displays the results within the context of CHC theory. The program also allows for the analysis of data to answer questions pertaining to the ‘pattern of strengths and weaknesses’ component in SLD evaluations as well as the test performance of individuals from culturally and linguistically diverse backgrounds.

The X-BASS System integrates the Cross-Battery Assessment Data Management and Interpretive Assistant, Pattern of Strengths and Weaknesses Analyzer, and Culture-Language Interpretive Matrix into a single program, covering the latest revisions of major batteries, including the new WISC®-V, WJ IV®, KTEA(tm)-3, CELF®-5, CTOPP-2, CAS2, and over 125 psychological batteries and 1,000 subtests, all classified according to CHC theory. Seven new batteries found in the updated 2.0 are:

1. Child and Adolescent Memory Profile (ChAMP)
2. Universal Nonverbal Intelligence Test-Second Edition (UNIT-2)
3. Reynolds Intellectual Assessment Scales-Second Edition (RIAS-2)
4. Feifer Assessment of Reading (FAR)
5. Feifer Assessment of Math (FAM)
6. Wechsler Intelligence Scale for Children-Fifth Edition: Integrated (WISC-V Integrated)
7. Woodcock-Johnson IV Early Cognitive and Academic Development (WJ IV ECAD)

X-BASS provides analyses for a wide variety of purposes, such as evaluation of test composites for cohesion, and guidance on follow up assessment and test selection. When warranted, X-BASS creates cross-battery composites that are psychometrically and theoretically defensible. Whether using a single battery or multiple batteries, X-BASS evaluates the effects of culture and language on test performance for English Learners. Following a comprehensive assessment, X-BASS evaluated data to determine if it follows a pattern of strengths and weaknesses (PSW) that is consistent with SLD. Compatible with Windows and Mac OS X, the internal database, single-instance data entry, automatic and integrated summary graphing, guided PSW analysis, and much more make X-BASS an essential one-stop within-battery and Cross-Battery Assessment solution.

• Interpret and present within-battery and cross-battery assessment findings efficiently and accurately
• Target analysis to answer specific questions for SLD evaluations
• Analyze empirical cognitive/academic relationships beyond relative magnitude of test scores
• Evaluate the effects of culture and language on test performance
• Customize referral-relevant batteries by selecting from the X-BASS database of hundreds of cognitive, achievement, neuropsychological, and speech-language subtests

The most up-to-date resource of comprehensive information for conducting cross-battery assessments


Cross Battery 2.0 pairs perfectly with the all new Essentials of WISC-V Assessment. Check out more information on the Essentials series at www.wiley.com/psychologyessentials.

The Cross-Battery assessment approach—also referred to as the XBA approach—is a time-efficient assessment method grounded solidly in contemporary theory and research. The XBA approach systematically integrates data across cognitive, achievement, and neuropsychological batteries, enabling practitioners to expand their traditional assessments to more comprehensively address referral concerns. This approach also includes guidelines for identification of specific learning disabilities and assessment of cognitive strengths and weaknesses in individuals from culturally and linguistically diverse backgrounds.

The School District can call Wiley Customer Care and place the order. Each individual user will be sent a personal Access Card with their own unique PIN.

Yes, an individual access card is needed for each download and that card is only good for a single download and for a single instance–no repeated downloading from the same access card. In other words, once the access “code” has been used, it is no longer valid for another download.

The access card is merely for the purposes of obtaining the program via download and can be used only once to get the program and place it on a computer or laptop. Once so downloaded onto a computer, it is run entirely from that computer and no further access or network connection is necessary as it is a standalone program.

It’s not recommended. The program is an individual file and should be downloaded directly to each user’s personal or work computer (or both) and not a file server or network drive (cloud). The program is not web based and it is not designed to be networked. Theoretically, the file could be set up on a server and it would permit multiple people to use the file in a protected manner, meaning that only one person could use the file at a time. This is not recommended because:

  • This could be risky because a corrupted or lost file will result in ALL of the data from a district’sentire evaluation staff being lost.
  • The file could hit its maximum case limit (500) much faster and reasonably large districtscould reach that number collectively in short order.
  • It could inconvenience some users who might have to wait if the file is already in use.

The X-BASS program is designed to be stored and run from an individual user’s computer. In this manner, each user will have full and on demand access to it wherever they are and whenever they want without any difficulties whatsoever.

Windows and Mac OS X compatible.

The Cross-Battery Assessment Software System (X-BASS) offers school, clinical, and neuropsychologists, as well as other assessment professionals a time-saving, efficient, expert method for evaluating the psychometric and theoretical validity of test scores and data based on principles underlying Cross-Battery Assessment (XBA). Evaluation of test score validity for cases involving English learners is also provided via the Culture-Language Interpretive Matrix (C-LIM). In general, X-BASS allows users to enter test data and information from virtually any standardized test for analysis that yields an interpretive summary of index/composite score cohesiveness and specific recommendations regarding the need for follow up testing. X-BASS incorporates rigorous statistical procedures for evaluation of test data that permit generation of the best representation of any broad ability construct according to modern CHC theory. In addition, X-BASS provides a mechanism for application of a Pattern of Strengths and Weaknesses (PSW) model for SLD identification that utilizes highly sophisticated statistical methodology specific to the domains selected for use in the framework to provide a complete and comprehensive analysis regarding the presence of a learning disability.

X-BASS is a single program solution that integrates the Cross-Battery Assessment Data Management and Interpretive Assistant, the Cross-Battery Assessment Pattern of Strengths and Weaknesses Analyzer, and the Cross-Battery Assessment Culture-Language Interpretive Matrix under one umbrella. X-BASS is compatible with Windows® and Mac OS X®. Please note: This item does not contain a disc; it is a product access card that requires a download from Wiley.
