I add a pre-printed post-it to the front of every child's assessment. Before taking, they fill out the info on the post-it (assessment name, goal, and their name). When I grade the assesment, I write their grade on the post-it specific spot and when I return them, they will see if they met their goal and if they did, they circle "heck yea!" If not, they will circle "not yet".
If they did meet their goal, they get to add their post-it to our #goalgetters wall
