FINDINGSOVERALL DIFFERENCESBecause reliable growth measures were needed, the majority of the analysis in this report is concentrated on a coregroup of students who had the following characteristics:They were in the same school in Fall 2009 and Spring 2010.They had valid scores in Fall 2009 and Spring 2010 in either Reading or Math or both.In addition, division by NWEA Project schools versus non-Project schools is limited to grades K-8 because there weren’tenough students in the upper grades in Project schools to make the comparison reliable. NWEA norm comparisons arelimited to grades 2-11.For more information about the selection of core students, please see the Methodology section. The following tablesshow the counts of BIE students in NWEA Project and non-Project schools for each subject and grade, as well as theaverage RIT score from Fall 2009 which serves as the baseline from which we measured growth. The average Fall RIT forstudents’ Virtual Comparison Groups (VCG) is shown next to the Project schools’ and non-Project schools’ average RITscores; note that the comparison groups for Project and non-Project schools are different. The national NWEAnormative score (Norm) for Fall is also shown. BIE average and VCG averages for Fall RIT should be very close since thecomparison groups were chosen in part based on this score.MATHTable 3: Fall Math RIT scores for Project, non-Project, VCG, and Norm groupsNumber of Students Fall RIT Score Fall RIT ScoreProjectProjectVCGNonprojectNonprojectVCGFall RIT ScoreNormK 226 262 131.5 133.2 132.9 134.81 329 269 153.7 153.7 152.8 154.62 383 612 170.6 170.5 172.4 172.4 179.53 343 651 180.9 181.6 183.4 183.4 182.14 379 629 189.8 190.1 193.8 193.8 203.05 333 604 197.7 197.8 201.6 201.8 211.76 360 574 204.1 204.7 208.0 208.1 218.37 299 582 208.8 208.7 213.2 213.7 224.18 273 596 214.1 213.9 218.4 218.4 229.39 61 589 231.610 67 474 235.211 63 395 237.112 44 154Total 3160 639112 | P a g e
READINGTable 4: Fall Reading RIT scores for Project, non-Project, VCG, and Norm groupsNumber of Students Fall RIT Score Fall RIT ScoreProjectProjectFall RIT ScoreAs is evident in the tables above, the average starting RIT score for Project students was slightly below the averagestarting RIT score for non-Project students in all subjects and all grades except 1 st . This is likely due to the fact that BIEchose schools for the NWEA Project based on low AYP performance. The average starting RIT score for all BIE students(Project and non-Project) and their VCG group was almost the same average score since each comparison group waschosen based on the student’s starting RIT score, as well as their school poverty rate and their geography. For moreinformation about the Virtual Comparison Group (VCG) comparison, see the Methodology. Both BIE students and theirVCGs were significantly below the national average.The performance of these different groups of students has been measured with several metrics. Fall 2009 RIT is thebaseline for this report. Spring 2010 RIT is the endpoint for this analysis. Raw growth is the difference between their FallRIT and their Spring RIT. Norm-indexed growth measures their growth against a national standard. VCG analysismeasures their growth against a group of similar students.The following charts show the average performance on Spring 2010 RIT scores for Reading and Math for NWEA Projectstudents, non-Project students and the NWEA norm students. A table of values for each group follows the two charts.VCGNonprojectNonprojectVCGNormK 243 268 132.8 134.9 134.0 134.61 340 285 151.7 151.7 150.0 152.92 384 616 164.9 165.4 168.3 168.3 179.73 349 641 174.8 176.0 179.6 179.6 191.64 376 616 183.7 183.8 189.1 189.0 200.15 336 575 189.5 189.6 195.8 195.8 206.76 357 566 195.8 196.2 200.3 200.3 211.67 302 605 199.4 199.6 205.2 205.3 215.48 267 586 202.2 202.7 209.0 209.1 219.09 58 617 220.910 68 526 223.911 64 421 225.212 44 149Total 3188 647113 | P a g e
