ATOS book levels are assigned using the ATOS readability formula.
For example, a book level of 4.5 means that the text could likely be read independently by a student whose reading skills are at the level of a typical fourth-grade student during the fifth month of school.
The content may or may not be appropriate for a fourth-grade student, which is why interest levels are also used.
The interest level reflects the judgment of the book's publisher and the professionals at Renaissance Learning. However, the final decision on whether the content of a book is appropriate for a particular student is the responsibility of school librarians, teachers and parents.
Within each interest level, you will find a wide range of book levels to support students who read at, above or below grade level.
AR Points
Every book that has an AR Reading Practice Quiz is given a point value. AR points are computed based on the difficulty of the book (ATOS
readability level) and the length of the book (number of words).
What is Interest Level (IL)?兴趣等级
Interest level is based on a book's content including theme, characterization, and plot. The interest level attached to the book indicates age group appropriateness. Interest level designations reflect the judgment of the book's publisher and the professionals at Renaissance Learning. We group content appropriateness into these categories: LG = Lower Grades (K-3); MG = Middle Grades (4-8); MG+ = Upper Middle Grades (6 and up); and UG = Upper Grades (9-12). Most MG+ books are marketed as YA (Young Adult) for Interest Level. However, the final decision as to whether the content of a specific book is appropriate for a particular student is the responsibility of school librarians, teachers, and parents.
What is ATOS Book Level (BL)? 文字难度等级
ATOS Book Levels are reported using the ATOS readability formula and represent the difficulty of the text. For example, a book level of 4.5 means the text could likely be read independently by a student whose reading skills are at the level of a typical fourth grader during the fifth month of school. (Of course the content may or may not be appropriate for a fourth grader which is why we also use Interest Levels.).
What are Accelerated Reader Points (AR Pts)? 文字难度和文章长度综合统计后得出的难度等级，划分的比较粗一点
Every book that has an AR Reading Practice Quiz is given a point value. AR Points are computed based on the difficulty of the book (ATOS readability level) and the length of the book (number of words). AR Points are a way of measuring how much reading practice your child is getting.
