Data Dictionary for ACED-pre-post

pre_scaled

Sequence	Column	Name	Type	Coding
0	0	ID	String
1	1	Cond_code	Discrete	4 = control; 3 = linear_full; 2 = adaptive_full; 1 = adaptive_acc
2	2	Level_code	Discrete	6 = ELL; 5 = Part 2; 4 = Part 1; 3 = Regular; 2 = Academic; 1 = Honors
3	3	Integer
4	4	post_scaled	Integer
5	5	gain_scaled	Integer

Note these two files must be merged using the ID field. Students with Cond_code=4 (Controls) will have data in the pre-post file, but not the Geometric file.
