Competency Unpacker

What This Skill Does

Takes a standard, learning objective, or competency descriptor — often written in abstract, compressed language — and unpacks it into four actionable components: observable indicators (what a student who has achieved this actually DOES), prerequisite knowledge (what must be in place first), common misconceptions (what typically goes wrong), and success criteria at multiple levels (beginning through extending). The output transforms opaque curriculum language into concrete, assessable, teachable components. AI is specifically valuable here because competency descriptors are deliberately compressed — a single sentence like "analyse how writers use language and structure to achieve effects" contains multiple skills, knowledge domains, and levels of sophistication that must be unpacked before they can be taught or assessed.

Evidence Foundation

Wiggins & McTighe (1998, 2005) established that effective curriculum design begins with clarity about desired results — and that most curriculum standards require significant "unpacking" before they can be translated into instruction and assessment. A standard that says "students will understand the causes of World War I" is not assessable until "understand" is defined in observable terms. Marzano & Kendall (2007) provided a taxonomy for classifying the cognitive demands of standards — distinguishing retrieval, comprehension, analysis, and knowledge utilisation — enabling teachers to identify what type of thinking a standard actually requires. Heritage (2008) and Popham (2007) demonstrated that unpacking standards into learning progressions — sequences of sub-skills from prerequisite to target — is essential for both instruction and formative assessment, because it reveals where students are and what they need next. Hattie (2009) found that clear success criteria (effect size 0.77) are among the highest-leverage instructional strategies, but only when they describe what success looks like in specific, observable terms — not when they restate the learning objective in different words.

Input Schema

The teacher must provide:

• Competency descriptor: The standard or objective to unpack. e.g. "Analyse how writers use language and structure to achieve effects and influence readers" / "Use ratio and proportion, including rates, to solve problems" / "Explain how changes in the environment may affect organisms"
• Student level: Year group. e.g. "Year 9"

Optional (injected by context engine if available):

• Subject area: The curriculum subject
• Curriculum framework: Specific standards framework (e.g., National Curriculum, IB, ACARA)
