Course Progression Overview
This standards progression guide outlines how students develop mastery across the four quarters of the course. Instruction is intentionally sequenced so that foundational concepts introduced early in the year are revisited, expanded, and applied in increasingly sophisticated ways.
QUARTER 1
Cells, Homeostasis & Matter/Energy
→
QUARTER 2
Growth, DNA & Development
→
QUARTER 3
Inheritance & Evolution
→
QUARTER 4
Evolution & Ecology

Standards shown with a solid maroon outline are priority standards (the Essential tier emphasized in the Scope & Sequence).
Standards shown with a dashed outline (and a “Plus” tag on the Standards tab) are Arizona Plus standards — honors/extension content beyond the Essential standards.
