Mastery rubrics.
One rubric per unit, plus the three demonstration rubrics. Every rubric uses the same three levels — Not yet, Approaching, Mastered — so the bar is identical for every student.

How the rubrics work
The grading philosophy behind every rubric — decisions not points, a vocabulary published in advance, three tokens that absorb a bad day, and how unit mastery becomes a letter grade.
Unit rubrics
A mastery rubric for each of the eight units. Each one names exactly what a student must be able to do — not how many points they earned — to reach Mastered.
Unit 01
Atomic Structure & the Periodic Table
Subatomic particles, isotopes, electron configuration, and periodic trends.
Unit 02
Chemical Bonding & Molecular Geometry
Ionic, covalent, and metallic bonds, Lewis structures, VSEPR, and polarity.
Unit 03
Stoichiometry & the Mole
The mole concept, balancing equations, limiting reagents, and percent yield.
Unit 04
States of Matter & Gas Laws
Kinetic molecular theory, gas laws, phase changes, and intermolecular forces.
Unit 05
Thermochemistry & Energy
Enthalpy, calorimetry, Hess's law, and bond energies.
Unit 06
Kinetics & Equilibrium
Reaction rates, collision theory, Le Châtelier's principle, and K.
Unit 07
Acids, Bases & Solutions
pH, titration, buffers, solubility, and concentration.
Unit 08
Electrochemistry & Redox
Oxidation states, balancing redox, and galvanic & electrolytic cells.
Demonstration rubrics
The three live demonstrations a student defends in person. These are the AI-proof assessments — you can't paste your way through any of them.
Demonstration
Acid–base titration defense
Defending your technique, endpoint, and calculations at the burette.
Demonstration
Timed qualitative analysis
Identifying an unknown ion or compound by test, against the clock.
Demonstration
Lab-notebook defense
Standing behind your recorded methods, data, and reasoning out loud.
