Do the Read Naturally reading levels correspond to grade levels?
Our levels do correspond to the grade levels they are named for in that the readability score for each story in each level falls within about 0.3 of the grade level named.
However, that does not mean that stories in our 2.0 grade level, for example, are appropriate for all early second graders. Rather, the 2.0 level is appropriate for students of any age whose instructional reading level is early second grade.
It is important to use the placement procedure to place students in the Read Naturally program. Proper placement is essential to provide the students with the right balance of challenge and success. And keep in mind that because of the audio support, students often work a half year above their instructional reading level.
We used the following readability formulas to level our stories:
- Fry and Spache readability formulas for levels .8 through 2.7.
- Harris-Jacobson readability formulas for levels 3.0 through 5.0.
- Dale Chall readability formulas for levels 5.6 and above.
To give you a frame of reference for how these formulas apply to other writing, we checked the readability of a few well-known works:
- Green Eggs and Ham by Dr. Seuss falls at 1.4 according to the Spache readability formula and low first grade according to the Fry readability formula.
- An excerpt from Harry Potter and the Philosopher's Stone by J. K. Rowlings falls at 5.0 on the Harris-Jacobson readability formula.
- The Miranda rights fall at 5.5 according to the Harris-Jacobson and Dale-Chall readability formulas.
- The Gettysburg Address falls at 6.8 according to the Dale-Chall readability formula.
- The second paragraph of the Declaration of Independence falls at 8.8 according to the Dale-Chall readability formula.
