⭐ Composite Score

A weighted combination of all four metrics: 35% Gateway + 20% Convergence + 35% Removal Impact + 10% Articulation. The best single indicator of overall instructional leverage, standards that score high here are worth prioritizing in both curriculum sequencing and diagnostic assessment.

→ Gateway (Forward Reachability)

Counts how many standards a student transitively unlocks by mastering this one - following the full chain of buildsTowards edges. A score of 80% means this standard sits upstream of 80% of everything else in your selection.

Strength: Directly actionable, missing a high-gateway standard creates cascading gaps.
Limitation: Favors early-grade standards structurally, since they have more downstream content.

← Convergence (In-Degree)

Counts how many other standards in your selection directly feed into this one. High convergence means many prerequisite threads merge here, this standard is a synthesis point where prior learning comes together.

Strength: Identifies standards that require broad readiness, useful for readiness screening.
Limitation: High in-degree doesn't tell you which prerequisite thread is the most important.

💥 Removal Impact

Simulates what happens if a student never learns this standard. Removes the node from the knowledge graph and counts how many other standards become unreachable from root nodes. A score of 60% means 60% of the maximum possible damage.

Strength: The most direct answer to "what breaks if they skip this?" — accounts for cascading downstream effects, not just direct connections.
Limitation: Computationally heavier than other metrics. Assumes a single removal; doesn't model multiple simultaneous gaps.

⬡ Articulation Points

A graph-theory metric (Tarjan's algorithm). A standard is an articulation point if removing it would split the knowledge graph into disconnected components. These are true structural bottlenecks, no detour exists around them.

Strength: Mathematically rigorous, these gaps genuinely cannot be routed around.
Limitation: Binary (yes/no), and may miss high-gateway standards that aren't structural cuts but are still critical.

How the graph works

Node size scales with the selected metric score. Node color represents content domain. Opacity reflects relative score, brighter = higher. Arrows show the direction of buildsTowards relationships. For state frameworks, knowledge graph connections are bridged through CCSS alignments.
