You might recall the column items I did about Bramble's calculations in his efforts to argue in behalf of vouchers. I won't get into his mistake about calling a comparison between student growth from one period to another period a comparison instead to student enrollment. He also made a mistake in basic math. The student growth from 1995 to 2005, he said, was 34,423. Projected student growth from 2005 to 2015, he said, is 154,752. He called that a stunning 450 percent increase.
Actually, it is a 350 percent increase. The CPA forgot to subtract the 34,423 from the 154,752 before doing his division to get the increase.
Now comes a pro-voucher mailer from dozens of business leaders recruited by legislative leaders to be soldiers in the voucher fight.
To make their case, the business leaders say student population growth over the last 10 years was 39,000. They say projected growth over the next 10 years will be 160,000. They call that a 400 percent increase.
Actually, and I learned this in public schools, the increase is 310 percent.
Cheers,
Paul Rolly
