We're not that good at Piaac either.

For years the OECD has been conducting tests around the world to assess the academic competency of 15-year-olders; the test is known as PISA. Readers will know that the U.S. does not do very well on these tests, which measure the average performance of students.

Now, the OECD has begun to measure the academic competency of the adult. This test is known as Piaac (Program for the International Assessment of Adult Competencies). We did not do too well here either. Here are some of the results of the latest test:

• Tied for last place with Italy and Spain.
• 18% Of U.S. adults with bachelor's degrees score at the top two levels, 24% of other countries do.
• Eighth from the bottom in literacy.

Maybe we're just stupid.
