Achieve3000 Literacy uses Lexile levels to scientifically match students to an appropriately leveled passage. Students receive a Lexile measure initially from the LevelSet assessment at the beginning of the school year. This is shown as a number with the letter L after it, such as 350L or 960L. From that point on, their Lexile levels are adjusted by the system on the 1st of each month as they work through the program.
In much the same way as Achieve3000 Literacy measures each student’s Lexile level, each reading passage is assigned a discrete Lexile measure, placing students and text on the same Lexile scale. Achieve3000 Literacy then uses this information to match readers to text.
When a student logs in, the system automatically finds the content that most closely matches the student’s Lexile level. Students read about the same topics as their classmates, but the difficulty level of the passage is tailored to their individual Lexile levels. For example, in a 6th grade class, Frances has a Lexile level of 960L, while her classmate has a Lexile level of 770L. Their reading selections will be about the same grade appropriate topic, but the level of the passage presented will be at different Lexile levels. Both students read a “tailor-made” article.
This method leads to an expected 75% comprehension rate—the content is not too difficult to be frustrating, but difficult enough to be challenging and to encourage reading progress. This comprehension rate is measured through the multiple-choice questions in the Respond step of a lesson. We encourage you to monitor your child's performance to ensure that they are scoring 75% and higher on activities. You can access this information by expanding the left menu in your Home Edition and selecting My Lessons. Toggle the drop down in the upper right of the table to Respond to see the first try score for each lesson completed by your child.
