State Performance Standards Database
The State Performance Standards Database aligns Lexile® and Quantile® measures with state proficiency standards for those states whose assessments are linked with the Lexile and or Quantile Frameworks and use the State Performance Standards Database. This database is updated annually as information regarding state testing dates and performance standards becomes available. When the State Performance Standards Database is used in conjunction with the MetaMetrics Forecasting REST API, student performance can be compared with the performance standards on linked high-stakes summative assessments.

  - About Score Interpreter
    - Scoring Service REST API
      The process of scoring student assessments and reporting results has evolved greatly over the years. From teachers sitting with paper-based answer sheets to bubble-sheets fed through a machine that produces a percent correct, technology has helped to enhance the process of scoring tests. While percent correct on an assessment can be valuable, many assessments benefit from reporting an estimate of the underlying student ability in an educational construct. These ability estimates provide indicators of status and can be used to monitor growth over time.
    - Forecasting REST API
      MetaMetrics Forecasting REST API uses a proprietary growth model to forecast student performance on an assessment that will be taken later in the school year. The Forecasting REST API uses recent results from interim/formative assessments published by its assessment partners to forecast performance. The forecasted performance is most commonly used* in relation to a state’s performance standards when both the interim/formative and the state assessments have been linked with the Lexile Framework® for Reading and/or the Quantile Framework® for Mathematics or reported directly using the Lexile® and/or Quantile® scales.

State Performance Standards Database

The State Performance Standards Database aligns Lexile® and Quantile® measures with state proficiency standards for those states whose assessments are linked with the Lexile and or Quantile Frameworks and use the State Performance Standards Database. This database is updated annually as information regarding state testing dates and performance standards becomes available. When the State Performance Standards Database is used in conjunction with the MetaMetrics Forecasting REST API, student performance can be compared with the performance standards on linked high-stakes summative assessments.

The State Performance Standards Database is delivered as an Excel file with five tabs:

It is often desirable to estimate student performance relative to state performance standards for students who may not be required to take a state summative assessment in a given year. For example, while high school students are typically not required to take state summative assessments every year, it is useful to know if students would be on track to demonstrate proficiency as defined by the state standards. To support the use of the MetaMetrics Forecasting REST API across all grades, MetaMetrics mathematically extends the cut scores, or performance standards, to grade levels that are not required to take summative assessments, thus creating a comprehensive set of performance standards. The extrapolated and interpolated cut scores can then be used to estimate student performance in relation to state performance standards.
