SDASP has formally adopted NASP's 2020 Professional Standards and Practice Model. The NASP Practice Model represents NASP’s official policy regarding the delivery of school psychological services. 

The 2020 model supports efforts to:

• Improve practitioner to student ratios of 1:500 

• Enhance recognition of and access to school psychologists' comprehensive skills and expertise across the 10 domains of practice

• Implement the 6 organizational principles necessary to ensure the systematic capacity for school psychologists to provide their comprehensive role

Implementation of the NASP Practice Model creates the capacity to make the best, most cost-effective use of school psychologists' skills and expertise, which are an existing but sometimes underutilized resource in schools. The Practice Model allows flexibility for agencies and professionals to develop policies and procedures that meet local needs, while also providing sufficient specificity to ensure appropriate, comprehensive service provision.
