Final answer:
Kevin's goal to raise his math grade lacks measurability, which is required to track progress and know when the goal is achieved. He should specify a target grade or percentage to make his goal SMART.
Step-by-step explanation:
When analyzing Kevin's goal, "I will raise my grade in math class by the end of the semester," to align with the principles of a SMART goal, it is evident that the characteristic it needs to improve is to be more measurable. To make his goal measurable, Kevin must define what raising his grade means, perhaps by specifying a target grade or a percentage increase. Without a way to measure his progress, it is difficult to track improvement and know when the goal has been achieved.
