The 70%-D Student G 36 74%-D Student H 40 gaps do not have to be of equal size i.e. you do 78%-C Student I 41 not need to have exactly the same number of 45%-F Student J 55 points between each tier. Separate the data into 83%-C Student K 60 tiers based on these breaks. Aim for somewhere 88%-B Student L 77 between 4 and 6 tiers. If the data does not 95%-A Student M 85 separate into tiers, see option two. Step Three: Assign each tier a Formal Assessment Student Name Pre-Test Score Growth Target % (points) Avg. growth target percentage 57%-F Student A 10 60% between 60 and 90. This will 90%-B Student B 11 60% be the percentage that 59%-F Student C 13 65% students in the tier try to 62%-F Student D 16 65% achieve on the post 65%-F Student E 25 70% assessment. You can base 73%-D Student F 29 70% these percentages on the 70%-D Student G 36 77% grading scale. The 74%-D Student H 40 77% percentages assigned to each 78%-C Student I 41 77% tier do not have to have the 45%-F Student J 55 85% 83%-C Student K 60 85% same distance between them. 88%-B Student L 77 93% See example below, the 95%-A Student M 85 93% percentage differences between each tier is different.

This will be the percentage that students in the tier try to achieve on the post assessment. You can base these percentages on the grading scale. The percentages assigned to each tier do not have to have the same distance between them. See example below, the percentage differences between each tier is different. Formal Assessment Avg. Student Name Pre-Test Score (points) Growth Target % 57%-F Student A 10 60% 45%-F Student J 55 60% 59%-F Student C 13 65% 62%-F Student D 16 65% 65%-F Student E 25 70% 73%-D Student F 29 70% 70%-D Student G 36 77% 74%-D Student H 40 77% 78%-C Student I 41 77% 90%-B Student B 11 85% 83%-C Student K 60 85%
