The SmartScore is based on IXL’s proprietary algorithm and is the best possible measure of how well a student understands a skill. With the SmartScore, the learning process is rewarded and your students are constantly reassessed.
When a student starts practising a skill, the SmartScore starts at 0. As the student answers questions correctly, the SmartScore increases. If a question is answered incorrectly, the score decreases. However, the SmartScore is not just based on the percentage of questions correct. It is calculated using many factors, including the number of questions completed, question difficulty and consistency, and offers superior accuracy in assessing student achievement.
A skill is mastered when the SmartScore reaches 100, but the number of questions it takes to master a skill varies with every student. To continuously motivate students, IXL recommends setting other practice milestones along the way to mastery. A score of 80 is good, and a score of 90 is considered excellent. When a student finally achieves skill mastery, you can be confident that they truly understand the skill.
