As an individual student or groups of students receive instruction and/or intervention, teachers may divide what they expect students to achieve by the end of year into shorter, measurable steps. Then teachers test students frequently (example: a five-minute test every two weeks) to check their progress towards those shorter steps. The teachers’ progress monitoring documentation, which may include graphs or data charts, serves as useful information for modifying the instruction and/or intervention, or for referring students to the next tier of help, as necessary.
