Some embodiments of an integrated student-growth platform for discovering, designating, and organizing heterogeneous instructional electronic resources based on observational assessments of students are disclosed. The student-growth platform is configured to establish and generate the best possible set of skills and resources for an educator to teach a group of students on a particular day and for a student to quickly progress to meet preferred educational standards. In one embodiment, the student-growth system includes a communication unit for sending and receiving data among users (e.g., teachers and students), an assessment platform, a planning platform, a learning-progression platform, an assignment platform, a mastery-maker platform, a Multi-Dimensional Response Item (MIRT) platform, and a reporting platform. The assessment platform 220 collects observation data for a target student, identifies one or more indicators to the learning-progression platform, which is coupled to the assignment platform, the mastery-maker platform, the MIRT platform, and the reporting module.
