I did this on Monday and got my money yesterday and trust me, all I did was mumble a few Spanish words I knew. Here are the exact instructions copied from where I found out about this:
Ordinate Corporation is looking for non-native Spanish speakers to participate in a research on an automated test of Spanish oral fluency. You should have studied Spanish for at least 2-3 years and be able to understand basic instructions in Spanish. Advanced speakers are welcome, but you should not be a native Spanish speaker. You must be at least 18 years old.
Participants will take a 20 minute automated Spanish test over the phone. The number to access the test is toll-free and should be called from a land line only (no cell phones or internet/VoIP phones). We will send you $10 via Paypal immediately upon your completion of the test.
For more information, or if you'd like to participate, simply e-mail Nicole at firstname.lastname@example.org. If you'd like to participate be sure to include these 3 pieces of information: Your native language, your gender, and your age range: 18- 25, 25-34, 35-44, or 45+.
