In accordance with WAC 392-170-055, the Bellevue School District uses multiple objective criteria for identification of students who are among the most highly capable.

Evidence of need for advanced learning services is determined by a district-level multi-disciplinary team. All decisions are based upon multiple criteria to include State assessment scores, district-level achievement measures, teacher and parent input, ability scores on the Cognitive Abilities Test 7 (CogAT 7), and achievement scores in reading and math on the STAR or IOWA Assessments. The CogAT 7, STAR and IOWA Assessments assist the multi-disciplinary team by providing information about each students’ ability and achievement level in comparison with their peers nationwide.

The following assessments and platforms are administered/utilized in school and student performance levels are available to us through the district data portal. The teacher does not have to provide any of these items.

Test Grades Administered
Text Reading Comprehension (TRC) K – 2
Freckle Math K – 5
Lexia K – 5
Alternative Reading Assessments K – 5 at Dual Language and Language Immersion Elementary Schools/Programs
STAR Reading 2 – 8
STAR Math (optional) 3 – 8
Smarter Balanced Assessment 3 – 8
Aleks Math 6 – 8
Power Up 6 – 8

Please Note: There are no weights assigned to various data points, but many are utilized in order to provide a clear picture of each student’s ability.  Qualifying decisions are based upon whether the total package of data indicates a need for services beyond the scope of the general education classroom.


Cognitive Abilities Test 7 (CogAT 7)

The Bellevue School District’s advanced learning services are designed to meet the academic needs of students determined through academic and cognitive testing to be 2 standard deviations or more above the mean, or roughly the 98th percentile and above when compared to the general population. The CogAT 7 tests a child’s cognitive reasoning ability and is scored based on a child’s birthday. For example, if a 6 1/2 year old answered 20 questions correctly, he would have a higher Standard Age Score than a student taking the same test and getting the same number of items correct who is 7 years old. In fact, the test scoring is done by increments of 3 months. So that a 6 1/2 year old student would be scored with students who are between 6 years and 6 months old to 6 years and 9 months old.

The Standard Age Score (SAS) tells you how your child compares to the other students in their age group. It has a median score of 100 with a standard deviation of 16:

• Sixty-eight percent of the general population will fall between 1 standard deviation below the mean and 1 standard deviation above the mean, with a standard age score between 84 and 116.

• Ninety-five percent of the general population will fall between 2 standard deviations below the mean and 2 standard deviations above the mean, with a standard age score between 68 and 132. Therefore, 95% of students are typically served in the general education classroom with differentiation to meet their needs.

• Students falling below or above 2 standard deviations (2.5% of the general population) tend to receive specially designed academic services. For example, an SAS score of 132 reveals that a child has an increased rate of development in reasoning skills that is beyond the norm for their age group.


STAR Assessments (STAR)

For every STAR assessment, your child receives a scaled score (SS), which is based on the difficulty of the questions and the number of correct answers. Scaled scores are useful for comparing your child’s performance over time and across grades. STAR Reading and STAR Math scaled scores range from 0–1400. Some STAR scores compare your child’s performance to a specific criteria or to a standard (criterion-referenced scores). STAR reports also include scores which compare your child’s performance to other students who have taken the same test (norm-referenced scores). The criterion- and norm-referenced scores are based on the scaled score.


IOWA Assessments (IOWA)

The IOWA tests a student’s academic knowledge and is scored by grade level. The grade percentiles on the IOWA designate the percentile of students on the Standard Curve of the same grade as your child who obtained lower scores. The median is the 50th percentile; the highest score is the 99th percentile.


Current Score Range of Students Identified in Need of Advanced Learning Services:

Kindergarten and First Grade (For BSD Students Only) 

  • Academic grade level equivalencies in math and reading 2 years above grade level
  • Other achievement data at or above 90% or Level 4
  • Demonstration of academic skill on BSD Performance Tasks

Domain-Specific Services in Elementary School (Grades K – 4)

  • LITERACY (VERBAL) DOMAIN: 132 SAS or above on CogAT Verbal, achievement results on the STAR or IOWA Reading at or above 95%, and academic grade level equivalency in reading 2 years above grade level
  • MATH (QUANTITATIVE) DOMAIN: 132 SAS or above on CogAT Quantitative,  achievement results on the STAR or IOWA Math assessments at or above 95%, and academic grade level equivalency in math 2 years above grade level
  • NON-VERBAL DOMAIN: 132 SAS or above on CogAT Non-Verbal

Self-Contained Services (SCS) in Elementary, Middle, or High School (Grades 2 – 12)

  • Two of the three CogAT subtests (Verbal, Quantitative or Non-Verbal) scores at or above 132 SAS (Standard Age Score) AND the third subtest score at or above 126 SAS
  • CogAT Composite score at or above 132 SAS
  • Achievement results on the STAR or IOWA Reading and Math assessments at or above 95%
  • Academic grade level equivalencies in reading and math 2 years above grade level
  • Other achievement data at or above 90% or Level 4

Please note: if your child is attending BSD on an inter-district transfer and is identified as in need of advanced learning, services are only provided through differentiation in the current school setting for which that transfer applies.


CogAT Standard Age Score Conversion to Percentile Ranks

Standard Age Score (SAS) is a normalized standard score, with a mean (average) of 100. Standard Age Scores of 89-111 are all within the average range. For example:

  • A student with a SAS of 100 on the Verbal Battery has the rate and level of development of verbal reasoning skills that are typical for his/her age group.
  • A student with a SAS of 125 on the Verbal Battery has a faster rate and higher level of development of verbal reasoning skills than the typical student in his/her age group.
  • A student with a SAS of 132 or above on the Verbal Battery has an exceptional rate and level of development of verbal reasoning skills that are considered to be in the advanced range for his/her age group.
