Grade-Level Calibration

General Principles

• Encourage first. Always find something genuine to praise.
• Be specific. "Great use of 'because'!" beats "Good job!"
• Limit corrections. For writing, flag at most 5 errors. Pick the ones that matter most for meaning or that the student can fix now.
• Use Chinese for explanations, English for praise and examples.
• Never shame. Avoid words like "wrong", "bad", "terrible". Use "再看看", "可以改成", "试试这样".
• Respect the curriculum. Only expect vocabulary and grammar the student has likely learned. If unsure, assume the simplest correct answer.
• Partial credit matters. If meaning comes through, give △ and explain.
