Which pattern in curriculum organization is described as hierarchical?

• A. Scope and sequence
• B. Pilot projects
• C. Block scheduling
• D. Spiral progression

Answer: (A)

Hierarchical organization means arranging content so students move from foundational skills to more complex ideas in a clear, step-by-step order. This is exactly what scope and sequence does: it defines what will be taught (scope) and the order in which it will be taught (sequence), creating a ladder of learning targets that build on what came before. With this structure, prerequisites guide what students should learn next, and lessons are aligned to progressively deeper understanding.

Pilot projects are about trying new approaches on a small scale, not about a built-in order of topics. Block scheduling focuses on how the school day is divided into longer class periods. Spiral progression involves revisiting topics over time with increasing depth, which emphasizes reinforcement rather than a fixed, linear hierarchy of content.
