IQ classification is the practice of categorizing human intelligence, as measured by intelligence quotient (IQ) tests, into categories such as "superior" and "average". [1][2][3][4]

50-69 — Mildly retarded Educable, can learn to care for oneself, employable in routinized jobs but require supervision. Might live alone but do best in supervised settings.

2023年11月16日 · IQ scores differ depending on which version of the test you take, but the average IQ score ranges are between 85 and 115. Shown below is an IQ chart classifying the range of scores according to the Stanford-Binet test.

1 天前 · Experts divide the types of cognitive impairment into four categories: mild intellectual disability, moderate intellectual disability, severe intellectual disability, and profound intellectual disability. The degree of impairment from an intellectual disability varies widely.

2025年1月30日 · People often talk about very high intelligence quotient (IQ) scores, often referred to as genius IQ scores, but what exactly do these numbers mean and how do they stack up? How do IQ scales break down scores into different IQ levels?

How does a 69 IQ compare to average scores? IQ results follow a bell curve, averaging 100. Most people, about 95%, score between 70 and 130. A 69 sits below this range, reflecting different thinking patterns. Approximately 1.9% of people test at 69 or lower. The positive aspect is that IQ is only one aspect of a person's capabilities!

2020年10月19日 · 69 and below: Extremely low intelligence Another IQ test places 85 to 115 as the average range, with 145 as the start of high IQ and 160 or higher as "genius-level." The American Psychiatric Association has developed the following ranges for very low IQ scores, to reflect level of disability:

Low ability: A Full Scale standard score of 69 and below and a percentile score of 2% or less. Individuals with this IQ profile are considered Developmentally Disabled (DD) or Mentally Retarded (MR) and are now categorized under the special education area of Developmental Cognitive Disability (DCD).

Mental deficiency used to be divided into the following sub-classifications, but these labels began to be abused by the public and are now largely obsolete: Borderline Deficiency (IQ 70-80), Moron (IQ 50-69), Imbecile (IQ 20-49) and Idiot (below 20).

实际上，iq计算中最重要且最易理解的数字是百分位数。 百分位数是与您（或测试者）相比，智力较低的人口百分比。 换句话说，就是您在智力上超过了多少百分比的人口。
