the first report on the effectiveness of US Teacher Preparation Programs 
(608 institutional programs rated)

        from the executive summary:

  "Once the world leader in educational attainment,
        the United States has slipped well into the
middle of the pack.

                Countries that were considered little more than educational backwaters just a few years ago have
leapt to the forefront of student achievement....

    There’s no shortage of factors for America’s educational decline" one of which is "the colleges and universities producing America’s traditionally prepared teachers....
     they have become an industry of mediocrity,
churning out first-year teachers with classroom management skills and content knowledge
inadequate to thrive in classrooms with ever-increasing ethnic and socioeconomic student diversity."

You get what you pay for
North Carolina continues to plummet in education spending per student and teacher salaries:
NC teacher salaries are now lower than those in all states except Mississippi, West Virginia, New Mexico, & Oklahoma (pages 19-20)...
and guess the state where salaries have dropped the most since 2001?  yep, it's  NC!

As to educational spending per student, we're 45th
(2 places higher)!  (page 55)

no need to  wonder why we NC is at the bottom of the heap
in average SAT
scores

(but the GOOD news is that NC is
in the top half
of states on prison spending!)
