As part of his pledge to "make America great again," Donald Trump wants to
spend less on schools and get better test scores.
Speaking at a rally in Tulsa, Okla., on Wednesday, Trump, a business
executive and a frontrunner for the Republican presidential nomination,
lambasted the performance of American public schools students compared to
their peers around the world. He said he was especially appalled because of
all the money that goes to education in the U.S.
"We're number one in terms of cost per pupil by a factor of, worldwide, by a
factor of many. Number two is so far behind, forget it," Trump said. "So we
're number one in the world in terms of spending. We're number twenty eight
in the world in terms of, where do we stand? We have third world countries
that are ahead of us, countries that you wouldn't believe, some countries
that you've hardly heard of." electionslug_2016_126x126.jpg
Trump said he envisioned a U.S. educational system that spends much less
than it does now, but gets top-drawer results.
The PISA Numbers
So do international test scores, and our national education budget, back up
what Trump's saying?
Let's turn to the most recent results from the Program for International
Student Assessment, commonly if not always fondly known as PISA. PISA is
administered in reading, math, and science. Scores remained stagnant in 2012
, the most recent year from which data is available. And here's how my
coworker Liana Heitin summarized the performance of U.S. students relative
to their counterparts on the 2012 PISA:
Nineteen countries and education systems outranked American students in
reading, up from nine in 2009.
Twenty nine nations and other jurisdictions outperformed Americans by a
statistically significant margin in math, up from 23 in 2009. (So Trump is
relatively close to the right answer when it comes to math.)
Twenty two education systems outperformed U.S. students, up from 18 in 2009.
Based on those comparisons, it's not clear where Trump got the figure that
we're ranked 28th as far as PISA goes. But Trump certainly isn't alone in
his general displeasure with the recent PISA resultsThumbnail image for
Donald-Trump-Sept-2015-blog-01.jpg.
As for Trump's claim that Third World countries are cleaning America's clock
? Once again, Liana helps you out with an interactive comparison of PISA
results. You can make value judgments for yourself through the interactive
chart, but here are a few comparisons:
In reading, countries that beat the U.S. by a statistically significant
margin include Estonia and Poland, along with countries like Canada, Finland
, and Japan.
In math, the U.S. got beat by countries such as Vietnam and Slovenia, along
with Chinese Taipei and Switzerland.
In science, Estonia, Poland, and Slovenia beat the U.S., along with
traditional PISA heavy hitters like Shanghai-China and Singapore.
(Some might also take issue with Trump's use of "Third World" instead of a
phrase like "developing nations.")
PISA has its detractors. It has been criticized by Tom Loveless of the
Brookings Institution for how it handles Shanghai's test scores, and more
broadly by academics and other education advocates who believe it warps
attitudes and approaches to K-12.
Cash on the Barrel
And what about Trump's claim that America spends more per student than any
other nation?
According to the 2014 "Education at a Glance" report from the Organization
for Economic Cooperation and Development, among the OECD's 38 member nations
and partner countries, the U.S. ranks fifth, at least when it comes to
expenditures on secondary education. In primary education, the U.S. ranked
fourth. So Trump's claim about the U.S. ranking tops in the spending
department is off the mark. But, at least as far as OECD is concerned,
America does rank relatively high.
Here's the OECD's chart on various U.S. educational expenditures, such as
the share of total goverment spending that goes to education (including
higher education), and how they compare to other nations:

But Wait, There's More
Trump wasn't quite done with addressing education, at least in a tangential
way.
"We're going to bring education back to the states and back to the people
and the parents ... We can't do any worse," Trump said later at the rally.
When it comes to shifting more K-12 policy power to states, the consensus is
that the Every Student Succeeds Act just does that.
And, as he does with some regularity, Trump took a shot at the Common Core
State Standards, which he has previously said are a "disaster."
Under his presidency, "Common core is out! The Second Amendment is in!"
Trump told the crowd.
ESSA requires states to adopt challenging academic standards, as my co-
blogger Alyson Klein just wrote. But ESSA also says the federal government
can't incentivize or coerce states into adopting a particular set of
standards. The only way a Trump administration could back up Trump's
campaign promise is through the passage of a new law banning common core
outright. (Congress, as well as the nation's governors and other K-12
officials, might wrinkle their nose at that idea.)
Ironically enough, Trump made that remark Thursday in Oklahoma, one of three
states to at least nominally repeal the common core. The Sooner State's new
standards haven't yet gone into effect.
Finally, on a related note, Trump recently made his views on gun control as
it relates to schools very clear: He wants to get rid of gun-free school
zones, which has been federal law for roughly 25 years. Once again, though,
it would require a new federal law to get the kind of change in policy Trump
wants.

我去过的学校太多了,2-4点下课的都有。
学区为了租 bus,有时候还要特意错开不同学校的上学和放学时间。
这样一辆 bus能够多 cover 几个学校。
