About Growth Planner API

This documentation is designed for developers, system integrators, product managers, and researchers who need to understand, implement, or evaluate the capabilities of this API.

The Growth Planner API provides authorized partners with secure, real-time access to key student predictive growth data. It analyzes a student’s reading and/or math performance data, reported as Lexile and Quantile summative or interim measures, and projects and monitors growth toward key milestones from as early as 3rd grade through grade 12.

The Growth Planner API supports three key tasks:

  • Plots the student's current measurement and any historical assessment data.
  • Projects the student’s likely growth through Grade 12.
  • Compares projected growth toward specific targets.

To plot measurements, the API requires the student's grade level, Lexile and/or Quantile measure, the month the test was administered, and an estimate to describe the part of the school year during which the test was administered. The measurements are then plotted at the appropriate place within the grade.

The API adheres to REST principles, returns JSON-formatted responses, and is secured using OAuth 2.0.

The API has two main endpoints:

Summative Endpoint

This endpoint exclusively accepts summative Lexile and Quantile measures derived from end-of-grade or end-of-course state assessments. For each measure submitted, the following information must be included: the date the measure was obtained, the student’s grade at the time, and the school year start date for that grade. The Growth Planner API utilizes this data to project the student’s growth in reading and math by the end of grade 12 in relation to college and career-ready targets.

Chart Generation – Summative Data

Graphs can be generated using either Lexile or Quantile student measures. Visual indicators on the graph show the recommended growth path, as well as various College and Career Readiness Ranges.

Interim Endpoint

This endpoint exclusively accepts interim Lexile and Quantile measures collected from periodic assessments administered throughout the school year. For each measure submitted, the following information must be included: the date the measure was obtained, the student’s grade at the time, and the school year start date for that grade. The Growth Planner API utilizes this data to project the student’s growth in reading and math by the end of grade 12, relative to college and career-ready or other defined targets.

Chart Generation – Interim Data

The graph plots the student's measures and makes a prediction for growth through 12th grade. Other optional visual graph indicators include a recommended growth path, as well as various College and Career Readiness Ranges.
