Which approach is LEAST consistent with effective early intervention practices?

Effective early intervention practices emphasize addressing developmental delays or difficulties as soon as they are identified to maximize positive outcomes.

Let's evaluate each option:

• Starting therapy as early as possible: This is a fundamental principle of early intervention, as earlier intervention generally leads to better results.
• Waiting until difficulties become severe before intervening: This approach contradicts the core idea of "early" intervention, which aims to prevent difficulties from escalating.
• Using a team-based approach: Effective early intervention often involves a multidisciplinary team to provide comprehensive support.
• Involving families in the intervention process: Family engagement is crucial for the success and generalization of intervention strategies.

Therefore, waiting until difficulties become severe before intervening is the approach least consistent with effective early intervention practices.

The correct option is B.

B. Waiting until difficulties become severe before intervening
