Parents of children with learning differences are often faced with the decision of which type of evaluation will best meet the needs of their child. This decision is important to ensuring that a child is supplied with the interventions/supports that will provide the greatest potential for success.
A psychoeducational evaluation usually includes an assessment of a child’s social history, intellectual abilities, and basic academic skills (reading, mathematics, spelling) as well as a psychological screening. A psychoeducational evaluation typically includes 2-4 hours of formal testing, depending on the school and/or individual approach of the clinician. The results of this type evaluation usually provide enough information to identify specific learning disabilities/differences as well as to pick up on clear psychological distress that is affecting a child’s functioning. A psychoeducational evaluation does not provide the clinical or psychometric data required to reliably capture cognitive difficulties associated with attention or executive functioning weaknesses (e.g., ADHD), Autism Spectrum Disorder, or more subtle psychological/social difficulties. This type of evaluation will provide recommendations for very general learning and counseling support.
A neuropsychological evaluation includes a detailed investigation of a child’s developmental, medical, social, and psychological history and an extensive testing battery that examines a child’s intellectual, academic, attention, executive functioning, language, visuospatial, visuoconstructional, memory, and fine motor skills. A detailed investigation of a child’s psychological/social functioning that includes both a clinical interview and a series of standardized parent, teacher, and self-report measures (if appropriate) is completed. This type of evaluation typically includes anywhere from 6 to 12 hours of testing. For many children, the inclusion of a direct classroom observation period is ideal and should be provided. The results of a neuropsychological evaluation are intended to identify not merely any intellectual or learning differences, but also any other cognitive or psychological difficulty that may be contributing to a child’s profile (e.g., language disorder, fine motor difficulties, attention problems). Data obtained in a neuropsychological evaluation will provide the information needed to generate a very comprehensive description of the child’s learning and support needs. This description should be used to identify the specific learning/therapeutic interventions that will work best to support the explicit needs of the child.
Dr. Lindsay Whitman conducts comprehensive neuropsychological assessments with children, adolescents, and young adults (ages 4-21). A neuropsychological evaluation is most helpful to parents who suspect that their child or teen may be struggling with a learning difference, developmental delay, intellectual disability, or is experiencing difficulty with memory, attention, or executive functioning skills (organization, planning). This type of comprehensive evaluation may also be helpful for children who may be struggling with behavioral, social, and/or psychological difficulties (anxiety, depression) that seem to be interfering with cognitive and/or academic functioning. Neuropsychological evaluations may be indicated for a child or adolescent in whom the reason for difficulty is largely unclear.

I field many questions from parents who are concerned with their child’s ability to read. Indeed, there are many confusing pieces of information on the internet that have the potential to mislead parents or teachers in understanding the reasons why one should (or should not) be concerned with a child or adolescent’s reading skill development. Other parents ask me to describe the ways that a neuropsychological or psychoeducational evaluation may help their child if indeed a reading difficulty is identified. This piece is intended to define dyslexia and discuss the process and value of a comprehensive evaluation process.
Dyslexia is another term for Reading Disorder, which is the technical term for reading difficulties used in the Diagnostic and Statistical Manual-IV-TR (“DSM”: the manual used by psychologists and social workers which lists and describes all possible diagnoses). In order to meet DSM-IV-TR criteria for reading disorder/dyslexia, a child’s reading skills must be substantially below what would be expected given her/his age, intelligence level, and education (as noted below, this objective “discrepancy” is NOT the only nor the most important criterion to consider). In addition, the child’s reading difficulty must interfere to a noticeable degree with both his/her academic performance and any general life skills that require reading proficiency. Finally, if the child has a sensory problem (e.g., vision difficulty), his/her reading difficulties must be over and above what would be expected based on the sensory difficulty alone.
There are two types of dyslexia: developmental dyslexia (e.g., an individual is born with difficulties) and acquired dyslexia (e.g., an individual ‘acquires’ reading difficulties secondary to a sudden occurrence such as a neurological injury). Developmental dyslexia is common among individuals with first-degree relatives with learning disorders. Thus, although dyslexia appears to be highly heritable, a child’s environment (e.g., how much the child’s parents encourage or model reading behaviors, how many books or reading materials are in the home) also seems to play an important role in the development of different types of reading profiles (Haiyou-Thomas, 2008).
Recent research shows that there are clear functional differences in the “brain systems” of children and young adults diagnosed with developmental dyslexia (Richlan, Kronbichler, & Wimmer, 2011). Research has also demonstrated that the functionality of disrupted “brain systems” has the potential to change upon exposure to high quality reading remediation (Shaywitz, Lyon, & Shaywitz, 2006). In other words, research suggests that with proper and timely reading intervention, the brains of children with dyslexia can change to function more similarly to the brains of children without dyslexia. This suggests that it is very important to identify early vulnerabilities to reading difficulties in children so that high quality programming may be initiated as soon as possible. In general, a younger child’s brain is more “plastic” or malleable than an older child’s brain, and thus, there is greater potential for more efficient change in younger children. (Identification of reading vulnerabilities before age six or seven is ideal.)
If I am concerned about my child, what kind of evaluation should a neuropsychologist do to evaluate whether or not my child meets the criteria for dyslexia?
When a child is referred for a neuropsychological or psychoeducational evaluation, there are often additional concerns (e.g., attention/concentration, mathematics skills, handwriting, impulsivity/behavior, mood, social skills) cited in addition to reading. For this reason, an evaluation should always be always tailored to the individual child. However, there are three parts of any evaluation in whom a reading disorder/dyslexia is diagnosed that are indispensable.
1. Standard scores on decoding and/or reading comprehension tests must be substantially lower than other children who are at her/his age and/or education level in order to diagnose dyslexia. It is important that children being compared have been exposed to the same level of education (e.g., if a child was very sick for a period of years and missed a substantial amount of school, it may not be entirely appropriate to directly compare her/him to his same-aged peer group).
2. In order to diagnose dyslexia, there must be substantial evidence (via history, clinical observation, and patterns of scores on a wide variety of tests) that establishes the extent to which the reading difficulty may be considered unexpected for this child (e.g., the child is very verbal, has a good vocabulary, and demonstrates otherwise strong academic or thinking or language skills).
3. Although recent research indicates that there may be different subtypes of dyslexia which include or do not include phonologic weakness (O’Brien, Wolf, & Lovett, 2011), the traditional understanding of dyslexia includes this clinical feature (e.g., clear and consistent difficulty linking sounds to letters). Thus, a thorough evaluation of dyslexia must thoroughly investigate the presence/absence of this quality in a child’s reading skill set via standardized tests of decoding. Other aspects of a child’s developing reading skills such as oral reading fluency, spelling skills, and reading comprehension are also central to an evaluation of dyslexia.
It is common for schools to rely heavily on the essence of criteria one or a “discrepancy model” (i.e., a 15-standard score point gap between a child’s intelligence level and reading level) to identify reading difficulties in children. This is concerning not only because there are important variations among testing materials between schools, but also because this approach does not necessarily capture the presence or absence of the “phonologic” component of dyslexia. Elimination of this component of an evaluation compromises accurate identification of children with these difficulties and the provision of a clear description of specific learning needs (e.g., type of intervention program, intensity of intervention format), leading to the possibility that a child will be matched with a reading program does not address his/her needs. Pairing a child with the wrong type of services may lead to what seems to be a lack of success when the true reason for difficulty is that his/her needs are not being appropriately supported.
So, in summary, why is a truly comprehensive neuropsychological/psychoeducational evaluation process important if I am concerned about my child?
As noted above, it is very important to identify a reading difficulty as early as possible in a child; the earlier a child is provided with the proper type of supportive services, the higher the chances of rapid progress with remediation. In addition, there are many classroom/school accommodations that can and should be provided to children with reading difficulties that will support them academically and hopefully reduce undue anxiety or stress. Examples of accommodations for children with dyslexia may include (depending on the child, of course) extended time for classwork and standardized tests, a quiet space to complete work, the provision of audiobooks or note taking services, and the use of visually-based learning aides. In sum, a neuropsychological evaluation will not only identify the needs of your child on a very comprehensive (and thereby likely more accurate) level, but also provide a thorough and practical list of the direct (e.g., classroom) or equally important indirect (e.g., therapeutic support to bolster self esteem or reduce anxiety) recommended services to best support him or her through their learning process.
