Supporting Children and Teens Through a diagnostic psychological evaluation

A psychological or psychoeducational assessment for children and adolescents can help to:

  • Understand learning profiles and academic strengths or challenges
  • Explore attention, executive functioning, and working memory (e.g., ADHD)
  • Clarify gifted or twice-exceptional profiles
  • Identify emotional, social, or behavioral factors affecting wellbeing
  • Support access to appropriate learning support or educational accommodations

Depending on the purpose of the assessment, formal tools may include the Wechsler instruments (WPPSI-IV, WISC-V, WAIS-5, WIAT-4, WMS-IV), D-KEFS Advanced, WRAML-3, BRIEF-2, BASC-3, RCMAS-2 – and where relevant, the SRS-2 may be used to assess social communication and interaction within the autism spectrum.

Gaining Clarity as an Adult Through a diagnostic psychological evaluation

A diagnostic psychological evaluation for adults may offer clarity regarding:

  • Possible ADHD or executive functioning challenges
  • Stress, burnout, anxiety, or emotional regulation concerns
  • Long-standing learning differences that were never formally assessed
  • Self-awareness, interpersonal patterns, or personality insight
  • Access to appropriate academic, workplace, or environmental accommodations

Many adults pursue assessment to gain not just answers, but also validation, deeper self-insight, and the clarity to move forward confidently.

Key Areas Explored in a diagnostic psychological evaluation

Every diagnostic psychological evaluation is tailored to the individual, but the following areas are commonly explored in order to ensure a full picture:

  • Focus and self-management — how attention, organization, and impulse control are managed in daily life
  • Social connection and communication — how a person reads social cues, forms relationships, and adapts across different cultural or interpersonal contexts
  • Thinking and learning style — how information is processed, understood, and problem-solved, including within multilingual or internationally diverse environments
  • Academic skills and environment fit — how reading, writing, and mathematical skills are developing relative to expectations and educational systems
  • Emotional wellbeing and regulation — how emotions are experienced, expressed, and managed — and what best supports confidence, safety, and resilience


Given the international and multicultural nature of life in Leidschendam, TPK Psychology Services conducts assessments that are sensitive to cultural, linguistic, and systemic factors. By recognizing the impact of multilingual environments and transitions between schools or countries, the insights and recommendations are grounded in real-world relevance.
