Leveling, also known as equalizing, is a process used in various fields to ensure that different elements are brought to a common standard or level. This can apply to audio mixing, where sound levels are adjusted to create a balanced listening experience, or in construction, where surfaces are made even to ensure stability and safety. In the context of education, leveling refers to grouping students based on their skill levels to provide tailored instruction. This approach allows educators to address the specific needs of each group, enhancing learning outcomes and ensuring that all students can progress at their own pace.
