Instructor rating versus performance


I am trying to figure out the following problem: Let's say we have driving instructor teaching a group of students how to drive and along the way the instructor provides ratings throughout the process,. We want to see if there is a relationship between instructor ratings and the students driving performance on the course's final driving test, and let's say the DMV's driving test, and then we collect driving performance over the next year (which would include looking at speeding tickets, other citations, etc.). Can you help me figure out which statistical test to use if the hypotheis is that there will be a positive relationship between instructor ratings and driver performance? Much thanks!
