Mental Health Assessment in Young Children

The IECMH-WC is the professional development component of a larger effort to support mental health assessment and diagnosis best practices for young children enrolled in Apple Health (Medicaid), including training in the DC:0-5, an internationally-accepted system for developmentally appropriate assessment and diagnosis of young children’s mental health. Additional components include updated reimbursement allowances and other billing supports for Apple Health providers (like the Apple Health DC:0-5 Crosswalk), which are available through the Health Care Authority’s webpage on mental health assessment for young children.

Washington State's IECMH Workforce

Babies, toddlers, preschoolers, and their families – including expecting families – are supported by professionals with a variety of backgrounds in multiple systems of care. Professionals who promote and support early mental health and social-emotional well-being include not only mental health providers, but a range of allied professional in fields such as early learning, home visiting, intervention, pediatric healthcare, and others.

IECMH Workforce Supports

A strong IECMH system that best supports young children and families in Washington requires partnerships between highly trained infant and early childhood professionals in a variety of roles, organizations, and systems of care.

The IECMH-WC, coordinated by WA-AIMH, offers free trainings and additional workforce supports - including DC:0-5 training and communities of practice as well as additional IECMH workshops - for professionals serving expecting families and children birth-5 enrolled in Apple Health (Medicaid). Goals of the IECMH-WC include:

  • Increase the number of professionals in Washington State who can better understand, assess, and diagnose infant and early childhood mental health issues.

  • Ensure that the professional development opportunities offered are equitable and accessible to all IECMH professionals, particularly those who have been historically underserved.


The Health Care Authority supports infrastructure needs for professionals and agencies providing Apple Health IECMH services, including Medicaid billing, the Apple Health DC:0-5 Crosswalk, and more.
