Cognitive & Developmental Assessment Aberdeenshire & Morayshire
Mr Jonathan Liddle is a qualified and registered psychological assessor. He offers cognitive and intelligence testing and development and attainment testing using highly specialised assessment tools. All assessments are conducted at his clinic based in Inverurie, Aberdeenshire. Cognitive and attainment testing can be used to help identify developmental learning difficulties including dyslexia, dysgraphia, dyscalculia, dyspraxia, ADD, ADHD, ASD, and General learning disability. Services are provided at a clinic in Inverurie and across Aberdeenshire & Morayshire.
Cognitive and intelligence testing is performed using the Wide Range Intelligence Test (WRIT). Development and attainment testing is performed using the Wide Range Achievement Test 4 (WRAT4).
The WRIT & WRAT4 provide evidence for concessions in education if necessary.
WRIT
The WRIT is a highly reliable assessment of cognitive abilities that can be used with individuals aged 4-85 years. The WRIT provides an estimate of cognitive ability for psychiatric or vocational rehabilitation evaluations; it also helps to identify learning disabilities, mental retardation, giftedness, neuropsychological impairments, and other exceptionalities. Taking less than 30 minutes to administer, the WRIT assesses both verbal and nonverbal abilities, yielding a Verbal IQ and a Visual IQ, which generate a General IQ when combined.
Features and benefits
WRAT4
The widely respected WRAT4 accurately measures the basic academic skills of word reading, sentence comprehension, spelling, and math computation. This quick, simple, psychometrically sound assessment of a student’s important fundamental academic skills serves as an excellent initial evaluation, re-evaluation, or progress measure for any student—especially those referred for learning, behavioural, or vocational difficulties.

Features and benefits
- Fast and reliable. Administration times average less than 30 minutes—yet the WRIT is as reliable as many lengthier measures.
- Covers an extended age range. Only one set of materials is needed to assess preschool children as young as 4 years to adults aged 85 years.
- Documents ability levels. Provides an estimate of cognitive ability for psychiatric or vocational rehabilitation evaluations.
- Helps to identify exceptionalities. The WRIT can help identify learning disabilities, mental retardation, giftedness, and neuropsychological impairments.
- Colorful, attractive, and engaging. Subtests encourage participation by individuals of all ages.
WRAT4

This quick, simple, psychometrically sound assessment of a student’s important fundamental academic skills serves as an excellent initial evaluation, re-evaluation, or progress measure for any student—especially those referred for learning, behavioural, or vocational difficulties.
Features and benefits
- Evaluates reading comprehension. The WRAT4 improves on its predecessor by adding a Sentence Comprehension subtest.
- Extension of norms. Grade-based norms increase the usefulness of the test in Grades K-12, and age-based norms extend to age 94 years, allowing for standardized assessment of older adults’ literacy skills.
- Parallel forms make retesting easy. The Blue and Green forms can be used interchangeably with comparable results, permitting retesting within short periods of time without practice effects. Alternate forms can also be combined into a single examination for a more qualitative assessment of academic skills.
- Time-efficient. Assessments can be obtained in as little as 15 minutes for younger children and as little as 30 minutes for older children and adults.
- Flexible. Use with individuals, or use with small groups (selected math and spelling areas) to identify those who need a more comprehensive evaluation.
- Reliable and valid. Standardized on a representative national sample of over 3,000 individuals ranging in age from 5 to 94 years, the WRAT4 has been shown to be highly reliable and valid.
- Word Reading measures letter and word decoding through letter identification and word recognition.
- Sentence Comprehension measures an individual’s ability to gain meaning from words and to comprehend ideas and information in sentences using a modified cloze technique.
- Spelling measures an individual’s ability to encode sounds into written form from dictated letters and words.
- Math Computation measures an individual’s ability to count, identify numbers, solve simple oral math problems, and calculate written math problems.
- A Reading Composite score is created by combining the Word Reading and Sentence Comprehension standard scores.
