I am a 10th grader and I have to do a report on proficiency tests. I'm having a little trouble finding information about them. Could you please let me know where I could find some?
There's lots of information out there about the individual tests, which you can obtain by typing the name of the test into a search engine.
Also, we have a whole section devoted to education. Here is a link to a chart of Math and Science Achievement from Around the World.
