What are the 100 best public elementary (K-6) schools in the USA? (if
not USA then Florida and Colorado) I would consider "best" as defined
by 1) highest possible reading/writing/math test scores, 2) lowest
teacher/student ratio, 3) highest percent of PHD or masters teachers,
4) highest $ spent per child, and then try to factor in reputation.

It won't be easy to answer the question as you'd like. One thing you
can do is search for "excellent" elementary schools in Colorado at
(http://www.cde.state.co.us/index_home.htm). There are about 60. Click
on "Accountability Reports," then on "Advanced Search."

Florida has 580 elementary schools that got an "A" rating from the
state Education Department. See
(http://www.firn.edu/doe/schoolgrades/).

You can also check out the federal list of "Blue Ribbon" schools at
(http://bcol01.ed.gov/CFAPPS/blueribbon/select_sch.cfm?selyear=2001).

Here's an article which helps illustrate why school rankings are a bit
suspect - "19 Of America's 'Finest' Schools Are 'Failing'", USA Today,
August 5, 2002.
