to help our students!
Three batteries that may be used independently or in any combination
WJ IV Tests of Cognitive Abilities
WJ IV Tests of Oral Language NEW!
WJ IV Tests of Achievement
The WJ IV emphasizes the identification of strengths and weaknesses by providing comparisons of both within each battery and across batteries.
This results in data that can be used to improve the outcomes for children and adults in a way that no other assessment can.
WJ IC ACH Subtests
20 subtests to measure reading, written language, mathematics and academic knowledge
Different forms were developed based on the practice of shared assessment and communication between professionals
Scoring and Norms
Reliability and Validity
Accessories and Interpretation Devices
The WJ IV comes with the 3 standard and extended batteries in easel formats and in ring formats to rearrange order when completing selective testing.
Examiner manual and protocols are also included
The examiners manual contains information on how to interpret the results and properly administer each battery
Technical manual is available online.
Any person administering the WJ IV needs:
Thorough knowledge of the exact administration and scoring procedures
Understanding of the importance of adhering to standardized procedures
Study the administration and scoring procedures and follow them precisely
To interpret competently any person needs:
Graduate level training in educational assessment
Background in diagnostic decision-marking
Professional Certification that includes formal training and code of ethics for the responsibility for rendering educational assessment and interpretation services.
Standards for Administrators
Cross Cultural Data
Well-developed and comprehensive resource for providing children with the best education possible.
Based on research and valid educational theories (evident through author bios)
Accessories and resources available provide so much information to help with administration and scoring
Comprehensive reports are elaborate and thorough and an excellent resource to any educator
My only wish is that we had access or it was required to read these reports because the results and strategies would be helpful for not just the individual students but would increase our "teacher toolbox" of strategies.
