The chapter will serve as an overview of the ASCA National Model and provide a clear connection with the translation from an aspirational ideal of school counseling to the reality of school counseling practice. The four main components of the National Model will be presented, including define, manage, deliver, and assess. This chapter will address and provide examples as to how these components are often offered in current models of PK–12 education—both in brick-and-mortar schools and online academies.
