What is the Student Learning Growth Score? The difference between Current test score and Predicted test score What is the Predicted Student Score?
What is the Predicted Student Score? 10 20 30 40 50 60 70 80 90 100… 85 CURRENT TEST 75 65 55 45 35 25 10 20 30 40 50 60 70 80 90 100… PRIOR TEST
What is the Predicted Student Score? 10 20 30 40 50 60 70 80 90 100… Answer: Average of the current scores of similar students 85 CURRENT TEST 75 65 The prediction describes typical growth observed among similar students. PREDICTED SCORE 55 55 45 35 25 10 20 30 40 50 60 70 80 90 100… PRIOR TEST
