Which statement best describes the core features of evidence-based intervention?

• A. Client-centered but sporadic practice
• B. Only repetition without errorless enablement
• C. Inflexible tasks with no environmental support
• D. Person-centered, strengths-based, repetitive, errorless, functional, environmental supports

Answer: (D)

Evidence-based intervention aims to fit the person, their strengths, and real-life goals into a structured learning plan. The best description combines three practical ideas: focusing on the individual’s needs and preferences (person-centered and strengths-based), using repeated practice to build skill while minimizing mistakes (repetitive and errorless learning), and ensuring the activities are useful in daily life with supports in the environment that help performance and transfer (functional tasks with environmental supports). This approach keeps learning meaningful, builds confidence through success, and promotes generalization beyond the learning session.

Why this fits: when you center on the person and their strengths, motivation and engagement improve, making the intervention more effective. Repetition helps solidify correct responses, while errorless learning reduces frustration and the risk of practicing incorrect responses. Choosing functional tasks ensures that the skills learned will matter in everyday life, and environmental supports—like prompts, cues, or adaptive tools—help the learner perform and carry the skills into other settings.

Why the other ideas don’t fit as well: practice that’s sporadic lacks consistency and data-driven progression. Repeating tasks without errorless strategies can reinforce mistakes and slow learning. Using rigid, nonfunctional tasks with no environmental supports makes it hard to apply what’s learned in real life, hindering generalization.
