Every child develops at their own pace, but it can be difficult to know when developmental differences may benefit from further evaluation. If you have concerns about your child’s development, a developmental assessment can provide valuable information and guidance.
A developmental assessment may be helpful if you have concerns about:
Our goal is to help you better understand your child’s unique developmental profile so you can feel confident about the next steps.

A developmental assessment is a comprehensive evaluation that examines how a young child is progressing across key areas of development. It helps identify strengths, areas where additional support may be beneficial, and whether further assessment or intervention should be considered.
Designed for children between 2 and 5 years of age, developmental assessments provide a clearer picture of how your child is functioning across different developmental domains. The information gathered can help guide decisions about educational supports, therapies, and other services that may benefit your child and family.
We strive to make the assessment process supportive, collaborative, and child-friendly.
The assessment begins with a meeting with parents or caregivers. During this appointment, we gather detailed information about your child’s developmental history, current functioning, strengths, and areas of concern.
This discussion helps us understand your child’s unique needs and ensures that the assessment is tailored appropriately.
Your child will participate in an assessment session while one parent or caregiver remains present. This allows us to observe your child’s skills in a comfortable and supportive environment.
Through structured activities and observation, we assess areas such as communication, social interaction, learning readiness, play skills, attention, emotional regulation, and adaptive functioning.
As part of the evaluation, we may complete structured interviews or questionnaires focused on adaptive skills. These measures provide important information about how your child functions in everyday situations.
Areas assessed may include:
Once the assessment is complete, we prepare a written summary of the findings and meet with you to review the results.

Cassandra Hillman White is the Owner and Clinical Director of Rocky Mountain Psychological Services (RMPS). A Registered Psychologist with more than 30 years of experience, Cassandra works with children, adolescents, parents, and families facing a wide range of developmental, emotional, behavioural, learning, and mental health challenges. She is known for her thoughtful case conceptualization, collaborative approach, and commitment to helping families understand both the challenges they are facing and the path forward.
Cassandra’s career began working with children with special needs and their families throughout Central Alberta. From supporting parents in their homes to consulting with daycare and preschool programs, she developed a deep appreciation for the importance of relationships, developmental understanding, and practical strategies that families and educators can use in everyday life. These early experiences continue to shape her work today.
Throughout her career, Cassandra has pursued extensive training across multiple therapeutic approaches, allowing her to tailor treatment to each client’s unique needs. Her clinical background includes Cognitive Behavioural Therapy (CBT), Internal Family Systems (IFS), Synergetic Play Therapy, Jungian Sandplay, Neurofeedback, Adlerian Therapy, Adlerian Play Therapy, and the Play Therapy Dimensions Model. While she draws from a variety of evidence-informed approaches, Adlerian principles and play therapy frameworks have become particularly influential in her current work with children and families.
Cassandra believes that effective therapy begins with understanding the whole person. Rather than focusing solely on symptoms, she works collaboratively with clients and families to explore the factors contributing to current challenges, identify strengths, and develop meaningful goals. She values creating clear treatment plans that are reviewed and adjusted over time, ensuring clients remain active participants in their own growth and healing.
As Clinical Director, Cassandra leads a multidisciplinary team dedicated to supporting children, adolescents, and families across complex presentations, including anxiety, depression, ADHD, autism, learning difficulties, emotional regulation concerns, trauma, behavioural challenges, and family relationship difficulties. She also works closely with schools, physicians, allied health professionals, and community agencies to help families access coordinated and effective support.
In addition to her clinical work, Cassandra serves as President of the Council of the College of Alberta Psychologists and is a Canadian Certified Play Therapist. She brings her commitment to ethical practice, professional excellence, and lifelong learning into every aspect of her work.
Outside of the office, Cassandra enjoys spending time with her four adult children, exploring nature, travelling, and continuing to learn. Her curiosity about people and their stories remains at the heart of the work she has loved for more than three decades.
