Abstract: A software platform creates and maintains a data structure in the form of a decision tree, with each location or node of the decision tree being associated with certain action steps that are automatically initiated, or are initiated in response to student assessment scores. The “trunk” of the decision tree includes a plurality of screening skills, while a plurality of branches extend outwards from each screening skill, with each branch node being a subsequent skill associated with the screening skill. Entire classes or individual students may traverse the tree based upon periodic time intervals (e.g., weekly assessment of screening skills) and results of prior assessments. Scores indicating mastery of assessed material will traverse the taker towards the trunk, while poor scores will traverse the taker away from the trunk into follow-up assessments. Interfaces are provided for teachers and administrators to monitor progress and generate materials for each node.
