[] Says only 7% of 6th grades will eventually graduate college in HISD. Since there are 200,000 students and assuming 1/13 of them are in 6th grade, there are around 15,400 6th graders. If 7% will eventually graduate college, that's 1077 students. The claim is that when YES serves 10,000 students, they will produce over 2,000 college graduates, tripling the number of college graduates from Houston, and that they will single-handedly produce twice as many college graduates as the rest of HISD. At YES North Central, there are 758 students 6th grade 161 = 21.2% 7th grade 158 = 20.8% 8th grade 118 = 15.6% 9th grade 114 = 15.0% 10th grade 96 = 12.7 % 11th grade 68 = 9.0% 12th grade 43 = 5.7%
 * Claim by YES quoted by Wendy Kopp that by 2014 YES will produce twice as many college graduates as the rest of HISD combined**
 * Analysis**

So, assuming that these percentages are typical of YES schools, when they grow to 10,000 total students, they would graduate 5.7% of 10,000, which is only 570 students. Then, even if all of them graduate college (which is quite unlikely) that would be very far from the 2000 college graduates they are claiming they will produce.

The best theoretically possible would be if they cured their attrition problem and got it so each class had the same number of students in it. Then there would be 14.3% seniors, which would be 1,430 graduates, but then ALL would have to graduate college.
