What is a key characteristic of professional learning communities?

• A. A focus on structured collaboration and shared norms.
• B. Isolated teacher practice without sharing.
• C. Top-down directives from administration only.
• D. Annual standardized testing.

Answer: (A)

Structured collaboration with shared norms among teachers is what defines professional learning communities. In a PLC, teachers regularly plan and reflect together, study student work, and use common expectations for instruction and feedback. They embrace collective responsibility for student learning and follow agreed-upon protocols to analyze data, discuss what’s working, and adjust teaching practices. This ongoing, data-informed teamwork creates consistent, improved practice across classrooms rather than isolated efforts or unilateral mandates.

Why this fits best: it emphasizes the collaborative culture and shared norms that drive ongoing improvement, which is central to PLCs. In contrast, isolated practice lacks collaboration, top-down directives undercut shared ownership, and focusing on annual standardized testing misses the continuous, collaborative work that actually improves learning outcomes. A concrete example is a team meeting weekly to review student work with a common rubric, plan targeted lessons, and adjust instruction based on results.
