WASHINGTON (AP) -- A new public school teacher in North Dakota works for a year on probation before getting job security. In Illinois, it's four years.
That's just one example of how teaching policies vary by state, according to a report today by the National Council on Teacher Quality.
The nonpartisan group says states have a mix of broken and counterproductive teaching policies.
One example involves teacher evaluations.
Just a quarter of states require annual reviews. Illinois requires one every two years. Hawaii, Missouri and Tennessee wait up to five years without a formal evaluation.
Illinois State Board of Education spokesman Matt Vanover says the agency welcomes the council's interest. But he says N-C-T-Q leaders acknowledge they're pushing a reform agenda.
Vanover says a comparable study by the U-S Chamber of Commerce gives Illinois an "A" grade on its teaching policies.
