SOURCE: Telephone surveys and transcripts. 

NOTE: Each impact was derived by subtracting the control group mean from the QOP group mean prior 

to rounding those means; thus, an impact might not equal the difference between the rounded 

means that are displayed. Estimates were obtained using weights to adjust for differences 

between respondents and nonrespondents in baseline characteristics, response rates to the first 

and second telephone surveys, and outcomes measured in the in-person and first telephone 

surveys. The evaluation sample had 580 QOP enrollees and 489 controls.

SOURCE: Telephone surveys and transcripts. 

NOTE: Each impact was derived by subtracting the control group mean from the QOP group mean prior 

to rounding those means; thus, an impact might not equal the difference between the rounded 

means that are displayed. Estimates were obtained using weights to adjust for differences 

between respondents and nonrespondents in baseline characteristics, response rates to the first 

and second telephone surveys, and outcomes measured in the in-person and first telephone 

surveys. The evaluation sample had 580 QOP enrollees and 489 controls.

NOTE: Each impact was derived by subtracting the control group mean from the QOP group mean. The 

weights used to derive the first column of weighted estimates adjust for baseline differences 

between respondents and nonrespondents. The weights used to derive the second column of 

weighted estimates adjust for differences between respondents and nonrespondents in baseline 

characteristics and response rates to the first and second telephone surveys. The weights used 

to derived the third column of weighted estimates adjust for differences between respondents and 

nonrespondents in baseline characteristics, response rates to the first and second telephone 

surveys, and outcomes measured in the in-person and first telephone surveys. The evaluation 

sample had 580 QOP enrollees and 489 controls.

 These estimates were derived by making the response rate for the QOP group equal to the response rate 

for the control group for each of the 11 schools. That is, if the QOP group had a higher response rate, we 

treated enough QOP group respondents as nonrespondents to lower the implied response rate to the level 

of the control group. The QOP group respondents that were treated as nonrespondents were the last ones 

to respond to the survey.
