A diagnostic psychological evaluation clarifies what condition or conditions are present, how severe they are, and what they mean for daily functioning. Dr. Meghan Semenick, Licensed Clinical Psychologist, conducts diagnostic psychological evaluations in Sandy, Utah for adults, adolescents, and children ages six and older, serving Salt Lake City and referral sources statewide.
Most people arrive at this evaluation because the existing answers have not held. A diagnosis was made quickly in a short appointment, treatment has not worked as expected, several providers have given different labels, or a school, employer, agency, or court now needs documentation that goes beyond a chart note. A comprehensive evaluation is slower and more thorough than any of those encounters, and it is designed to produce an answer that can be relied on.
When Diagnostic Clarification Is the Question
The most common referrals involve conflicting or uncertain diagnoses, treatment that has not produced the expected response, a complex presentation that does not fit a single category cleanly, a longstanding pattern that has never been formally assessed, or a documentation requirement from an outside party. Referrals come from individuals and families, treating providers, schools, agencies, disability programs, and attorneys.
Diagnostic questions commonly addressed include:
- Autism and related neurodevelopmental presentations
- Intellectual disability and adaptive functioning
- Serious mental illness including psychotic and bipolar spectrum conditions
- Mood and anxiety disorders
- Trauma-related conditions
- Personality functioning
- Behavioral concerns in children and adolescents
It is worth naming what an evaluation is for. It is not a formality performed to produce a conclusion someone has already decided on. An assessment that can only confirm and never disconfirm is not an assessment, and a report that reaches a predetermined answer will not withstand scrutiny by the school, insurer, agency, or court that requested it.
What the Evaluation Involves
The process begins with a consultation to establish the referral question — what decision the evaluation needs to inform, and who will read the report. That determines scope, since an evaluation for treatment planning, one for an accommodation request, and one for a legal proceeding require different emphases and different levels of documentation.
The assessment generally includes:
- Review of relevant records
- One or more clinical interviews covering developmental, medical, educational, occupational, and psychosocial history
- Standardized measures selected for the referral question
- Collateral information from family, providers, or school where appropriate and authorized
Collateral information carries particular weight in developmental and neurodevelopmental questions, where the person's own recollection of early childhood is necessarily limited.
Length varies considerably. A focused question may be answered in a single appointment plus records review; a complex differential involving cognitive and adaptive measures may require several. Scope is settled in writing before the evaluation begins so that the time commitment and the cost are known in advance.
Differential Diagnosis: Why Presentations Get Misread
Psychiatric conditions share symptoms extensively, and the overlap is where most diagnostic error lives. Difficulty concentrating is a feature of attention disorders, depression, anxiety, trauma-related conditions, sleep deprivation, and the side effects of several common medications. Social difficulty appears in autism, social anxiety, depression, and psychotic-spectrum conditions. Emotional volatility can reflect a mood disorder, a trauma history, a personality pattern, or a neurodevelopmental condition. Any of these can be assigned a plausible-sounding label in twenty minutes, and frequently is.
A comprehensive evaluation works through the alternatives rather than stopping at the first fit. That means examining onset and course, the context in which symptoms appear and do not appear, developmental history, response to prior treatment, and whether the pattern is lifelong or represents a change — and then stating not only what the findings support but what was considered and ruled out, and why.
The result is sometimes that a prior diagnosis was accurate and simply incomplete, sometimes that two conditions are present rather than one, and sometimes that the original label was wrong. All three are useful outcomes. A misdirected diagnosis often means years of treatment aimed at the wrong target, which is the actual cost of leaving the question unexamined.
Autism and Neurodevelopmental Questions
Autism assessment in older children and adults raises a distinct set of challenges. Many people evaluated later in life have spent years compensating — learning social rules explicitly, rehearsing interactions, masking discomfort — which can make presentation in a brief appointment look unremarkable while the underlying effort and the exhaustion it produces go unrecorded. Presentations also differ in ways that led to substantial historic under-identification, particularly in women and in people whose academic performance was strong.
A thorough assessment therefore reaches beyond the interview: developmental history from childhood records and, where available, from family; the pattern of functioning across settings rather than in the consulting room alone; the specific supports and accommodations a person has constructed for themselves; and the differential against conditions that share territory with autism, including social anxiety, trauma-related presentations, and personality patterns.
The report describes functional strengths and needs, not only whether criteria are met. For most people the diagnostic label matters less than the specific account of what is difficult, why, and what supports would help — which is also what schools, employers, and disability programs actually act on.
Intellectual and Adaptive Functioning
Questions about intellectual disability arise in:
- Educational planning
- Disability and benefits determinations
- Guardianship and supported decision-making questions
- Service eligibility
- Legal proceedings where cognitive limitation is relevant
The assessment addresses both intellectual functioning and adaptive functioning — the practical, social, and conceptual skills a person uses to manage everyday life — because the diagnostic frameworks require both, and adaptive functioning is the part most often left undocumented.
That omission has consequences. A person may test in a range that does not by itself establish intellectual disability while having substantial difficulty with money, transportation, medication, employment, and independent living, and an evaluation that reports scores without documenting daily functioning gives the decision-maker only half the picture. Adaptive functioning is assessed through structured information from people who know the person across settings, which is why collateral participation is requested.
Children and Adolescents Ages Six and Older
Evaluations are available for children and adolescents from age six. For younger clients the referral question is generally clinical rather than legal: what is driving the behavior, what the diagnosis is, what the child needs, and what should be recommended to a family, a treating provider, or a school. Parents and guardians are involved throughout, and developmental history is gathered directly from them.
Where an adolescent is involved in a justice-system matter, a juvenile forensic evaluation is the appropriate referral instead. The distinction is one of purpose, not merely of age. A justice-involved evaluation is prepared for a court or agency, the confidentiality terms are different, and the referral question is set by the legal proceeding. Those two things should not be blended into one appointment.
Schools, Accommodations, and Disability Determinations
An independent psychological evaluation and a school evaluation are not the same instrument. Eligibility for special education services is determined by the school team under its own legal framework and criteria, and an outside report does not by itself establish eligibility — the school must consider it, but the determination remains theirs. Independent evaluations are nonetheless valuable where a school evaluation was declined, where the family disagrees with its conclusions, or where the diagnostic picture is broader than the educational question the school assessed.
Diagnostic evaluations are also used to support requests for academic accommodations, workplace accommodations, and disability or benefits determinations. Each of those programs sets its own documentation requirements — how recent the testing must be, which domains must be addressed, and what form the report must take. Those requirements should be identified before the evaluation begins, because a thorough report that omits a required element will be returned, and repeating an evaluation is expensive.
When a Diagnostic Evaluation Is Also a Forensic One
Where an attorney, court, or agency requests the evaluation, the posture changes even if the diagnostic question is identical. The client becomes the referring party rather than the person being evaluated, the report goes to the referral source under terms agreed in advance, and the examinee is told at the outset what will be shared and with whom. That framing is set before the evaluation begins, not adjusted afterward when someone asks for a copy.
Diagnostic clarification is frequently the right first step in a legal matter, because a specific forensic question — competency, criminal responsibility, parenting capacity, risk, mitigation — often cannot be answered sensibly until the underlying diagnostic picture is understood. Counsel unsure which referral applies should raise it at consultation; scoping the wrong evaluation is the most expensive error in this work.
What This Service Is Not
This is not therapy, and no ongoing treatment is provided. It is not medication management — this practice does not prescribe, and where medication questions arise the report makes recommendations for a prescribing provider rather than directing treatment. It is not an emergency or crisis service.
It is also not a document-issuing service. Letters certifying a predetermined diagnosis, support-animal documentation, and cannabis certifications are not provided. Where a report supports a particular conclusion the report says so; where the findings do not support what was hoped for, the report says that instead, which is the only reason the ones that do support a conclusion carry any weight.
Reports, Timeline, and Cost
The report sets out the referral question, records reviewed, procedures used, relevant developmental and clinical history, behavioral observations, findings, diagnostic reasoning including the alternatives considered, functional impact, stated limitations, and recommendations. It is written to be understood by the person who has to act on it — a family, a treating provider, a school team, an agency, or counsel — rather than in language that requires a psychologist to interpret. Findings are reviewed directly with the client or family so that the report is not the first time its conclusions are encountered.
Timeline depends on records, the number of appointments the assessment requires, collateral availability, and any external deadline. Expedited scheduling may be available for school, legal, or program deadlines. Cost depends on scope — the measures required, the number of appointments, records volume, and collateral contacts — and fees are quoted in writing after an initial consultation. The office is at 9265 Highland Drive in Sandy, Utah, about twenty minutes from downtown Salt Lake City, with virtual appointments available where remote administration is appropriate.
Frequently Asked Questions
What is a diagnostic psychological evaluation?
A comprehensive assessment that clarifies which conditions are present, how severe they are, and how they affect functioning. It combines records review, clinical interview, standardized measures, and collateral information, and produces a written report with reasoning and recommendations.
How is this different from a diagnosis from my doctor or therapist?
A diagnosis made in a brief appointment relies largely on presenting complaints. A comprehensive evaluation gathers developmental history, standardized data, and collateral information, works systematically through the alternatives, and documents what was ruled out and why — which is what outside parties require when documentation is at stake.
What ages are evaluated?
Adults, adolescents, and children ages six and older. For adolescents involved in a justice-system matter, a juvenile forensic evaluation is the appropriate referral rather than a diagnostic one.
Can adults be evaluated for autism?
Yes. Adult and later-adolescent assessment accounts for years of learned compensation that can mask presentation in a brief appointment, and draws on developmental history and functioning across settings rather than the interview alone.
Will this evaluation get my child an IEP or 504 plan?
Not on its own. Special education eligibility is determined by the school team under its own framework, and the school must consider an outside report without being bound by it. Independent evaluations are still useful where a school evaluation was declined, is disputed, or addressed a narrower question.
Can the report support an accommodation or disability request?
Often, yes. Each program sets its own documentation requirements — recency, domains covered, and report format. Those requirements should be identified before the evaluation begins so the report meets them the first time.
How long does the evaluation take?
It depends on the question. A focused referral may need one appointment plus records review; a complex differential involving cognitive and adaptive measures may take several. Scope and timeline are settled in writing before the evaluation begins.
Do you prescribe or manage medication?
No. This practice conducts evaluations and does not prescribe. Where medication is relevant, the report provides recommendations for a prescribing provider to consider.
How much does a diagnostic evaluation cost?
Cost depends on scope — the measures required, the number of appointments, records volume, and collateral contacts. A written quote follows an initial consultation.
Request a Case Consultation
Request a consultation to discuss the diagnostic question, who will need to read the report, records, and any deadline. Virtual and in-person appointments are available, with expedited scheduling considered for school, legal, and program deadlines.
