Testing Rewards

I have really been working hard with my kids to get ready for their MAP test the next couple weeks. We have been working on reviewing how take a test and some strategies that we might use on the test. I will continue working with the students until testing is finished. I will be meeting with them over the next couple days to go over their test scores and their goal that they need to meet. I feel that they should be reminded and be aware of their goals on their tests. In past schools that I have worked at, testing and reaching their goal has been a bigger deal. I had kindergartners pledging at the beginning of the year to try to get a certain score on their NWEA test during the year. Each time they took the test, which was three times a year, they were able to win a reward if they passed the score or meet their goal. This reward was worked into the grade level for each time we took the test. The students could win things from happy meals to a picnic at the park depending on what the teachers chose for the year. I am not sure where this money came from for the students to receive this reward, but the principal always made it happen. I am planning on giving my students who make their goals in reading and math a reward. I have not come up with one yet, but might have the students come up with ideas and then have a vote. I do understand that all of my students are working towards their goal, but I feel there should be a reward for those who made their individual goals. Does anyone have any ideas or suggestions on this topic?
