Most educators are familiar with the industry-standard Lexile Framework for Reading. Millions of students receive a Lexile score every year. More and more states are now adopting Lexiles and including them in their confidential student reports from their statewide summative assessments.
For those who may be unfamiliar with Lexiles, the Lexile score is a standard measure of reading ability (for students) and text difficulty (for written works). Students receive Lexile scores from PASeries and other assessment instruments. Texts can also be analyzed and given a Lexile score of their difficulty. When students are matched to texts with a similar Lexile level, they will comprehend approximately 75% of the material. This challenges students but insures that the text is not so difficult that they become frustrated readers.
MetaMetrics Inc., the creators of Lexiles, maintains a host of Lexile resources on their
Lexile website.
The Quantile Framework for Mathematics is a new standard measure of mathematics achievement also created by MetaMetrics.
PASeries is the first formative assessment instrument to use
Quantiles.
Quantiles are similar to Lexiles in that they provide a standard measure of achievement that may be applied across student populations locally, statewide, and nationally. Once a student’s Quantile score is known, instructors may view the
QTaxons (specific mathematical concepts, skills, or topics) and relate a student’s score to the curricula to determine if a student is on pace with instruction.
The Quantile achievement level of a student also provides a view into the precursory QTaxons that the student has demonstrated mastery of. That is, it indicates the skills, topics, or concepts that a student needed to master in order to achieve the Quantile level demonstrated. This is particularly useful when examining the achievement of struggling students. Precursory skills, topics, and concepts can be reviewed with the student to identify areas of weakness and aid in putting them back on target. States are also beginning to adopt Quantiles as they have Lexiles as a standard measure of achievement.
