One reason Common Core is a good thing

A former student once told me that he'd lived in five states since kindergarten. While that's a high number, he wasn't the only student I've ever known who had done that.

I'll grant that while students who've lived in three or more states are unusual, students going back and forth between states isn't. At least, it's not so unusual that it wouldn't affect academic outcomes for a decent number of students.

It's hard to get data on this specific issue because data tracking students making intra-district moves in a school gets lumped into data tracking students moving state-to-state. Regardless, the general facts on student mobility are sobering. From a 1994 U.S. General Accounting Office study -- and it's a safe assumption that the mobility rate has only increased since then: (Hat tip Hoover Institution)

• About 17 percent of all third graders—more than a half million—have changed schools frequently.
• More than 24 percent of third graders have attended two schools since the first grade.
• Of third graders from low-income families (incomes below $10,000), 30 percent have changed schools frequently, compared with approximately 10 percent from families with incomes of $25,000–$49,000 and 8 percent of children in families with incomes of $50,000 or more
• About 25 percent of third graders in inner-city schools have changed schools frequently, compared with about 15 percent of third graders in rural or suburban schools.

And it damages achievement:

• Overall, third graders who have changed schools frequently are two and a half times as likely to repeat a grade as third graders who have never changed schools (20 versus 8 percent).
• For all income groups, children who have changed schools frequently are more likely to repeat a grade than children who have never changed schools.
• Children who changed schools four or more times by the eighth grade were at least four times more likely to drop out than those who remained in the same school; this is true even after taking into account the socioeconomic status of a child’s family.

Moving from school to school within a district is something that could be addressed by policy. Students moving from state to state is another challenge altogether. It seems to me that the best solution is to make the academic transition as smooth as possible. Hence the need for grade-level expectations to be as consistent as possible from district-to-district and state-to-state. 

Of course, not all agree. South Carolina Gov. Nikki Haley sees, in the words of Education Secretary Arne Duncan, "a conspiracy theory in search of a conspiracy."

From USA Today:

"Just as we should not relinquish control of education to the Federal government," [Haley] wrote in a letter to a state lawmaker, "neither should we cede it to the consensus of other states."

With an education system ranked dead last in achievement, God forbid that South Carolina learn anything from other states. 

And, of course, if Arne Duncan is in favor of something, then Diane Ravitch opposes it. From the same USA Today article:

Last month, New York University education historian Diane Ravitch, a vocal Duncan critic, blasted the standards, writing in The New York Review of Books that they've never been field-tested. "No one knows whether these standards are good or bad, whether they will improve academic achievement or widen the achievement gap," she said.

A question for Ravitch: How will decreasing the differences between academic expectations state-to-state widen the achievement gap? 

I could see a problem if Common Core standards were less rigorous than the typical set of state standards, but they don't seem to be. I'm spending the year moving from Tennessee English I standards to Common Core. The latter are tougher -- which is a good thing. I'm also familiar with English I standards in Pennsylvania, Mississippi, and Texas** -- Common Core seems to be a step up for all of them. 

That aside, I suspect that some of the real winners will be these students who have high mobility rates, particularly those who change districts.

After all, does anyone envision a future where families less frequently move from city to city?

**During the past few years, I've spent more time than I'd care to admit perusing different states' standardized tests. It's yet another one of my nerdy hobbies.
