The Lexile Framework for Reading is a scientific approach that places both the reader and text on the same developmental scale, making it easy to connect your child with books targeted to their reading ability.
| Grade Level | Lexile Level (based on the 50th and 90th percentiles) |
| K | BR160 ---- L150L |
| 1 | 165L ---- 570L |
| 2 | 425L ---- 795L |
| 3 | 645L ---- 985L |
| 4 | 850L ---- 1160L |
| 5 | 950L ---- 1260L |
| 6 | 1030L ----- 1340L |
| 7 | 1095L ---- 1410L |
| 8 | 1155L ---- 1470L |
| 9 | 1205L ---- 1520L |
| 10 | 1250L ---- 1570L |

1295L ---- 1610L |
| 12 | 1295L ---- 1610L |
Percentiles from national student norms describe how a student performed compared to all of the students measured.
Performance standards are set by states and assessment developers. Labels such as “basic” or “proficient” are often applied to each standard.
So, a student at the 50th percentile could be both at the mid-point of student norms and “not meet grade-level performance standards”.
