You may already know Americans don't have the best record when it comes to financial or tax literacy. In particular, many younger workers could use a refresher on managing and growing money properly.

But it turns out a lack of financial literacy isn't just a problem in the United States — and it starts early. About one in four 15-year-olds in the 15 countries and regions that took part in the latest OECD Programme for International Student Assessment test of financial literacy were unable to make "even simple decisions on everyday spending," while only one in 10 can understand complicated issues like income tax: perhaps an argument for better financial education in high school?

"While almost 60% of these students have a bank account and more than 60% earn money from some type of working activity, many cannot recognize the value of a simple budget, let alone understand a bank statement or a pay slip," Angel Gurria, OECD secretary-general, said in remarks on the report's release Wednesday. "This is shocking!"

Just 12% scored at the highest levels of financial literacy, while 22% percent scored below the baseline level of proficiency, according to the report. American teens scored just above average, while Chinese students scored the highest. However, as Bloomberg points out, international comparisons are tricky because in some countries only a "relatively well-educated segment of the population took the test," which could skew the results.

Let's see how well you can do: Below are five questions from the PISA test. Scroll down for answers at the bottom of this story.

How'd you do on the quiz? Performing well can be a sign that you're better set up for financial success, whether that means growing your money through investing or simply avoiding scams.

The OECD argues that schools have a huge role to play in leveling the financial literacy playing field, given the correlation between a teen's family's financial background and their scores: "The fact that students' financial literacy skills are strongly correlated to their socioeconomic status — or whether they or their parents are foreign-born — means that not all students have the same opportunities to acquire financial literacy if they rely solely on what they can learn from their family," the organization wrote
