Total testing time is around 45 to 60 minutes, depending on the child's age and the number of subtests given. Raw scores are based on the number of items answered and are converted into a standard age score corresponding to age group, similar to an IQ measure.
Intelligence testing requires a clinically trained examiner. The Stanford-Binet intelligence scale should Teenage girl taking an intelligence test. Children with physical disabilities may require certain accommodations when taking the test, such as extra time for tasks, rest breaks, or instructions received in an alternate format e.
The examiner should be made aware of a child's potential limitations before the day of the test so that appropriate accommodations are available. It is a standardized test, meaning that norms are established during the design phase of the test by administering the test to a large, representative sample of the test population in the case of the fifth edition, data from the U. The test has a mean, or average, standard score of and a standard deviation of 15 for composite scores subtests have a mean of 10 and a standard deviation of 3.
The standard deviation indicates how far above or below the norm the subject's score is. For example, an eight-year-old is assessed with the Stanford-Binet scale and achieves a standard age score of The mean score of is the average level at which all eight-year-olds in the representative sample performed.
This child's score would be one standard deviation above that norm. While standard age scores provide a reference point for evaluation, they represent an average of a variety of skill areas. A trained psychologist evaluates and interprets an individual's performance on the scale's subtests to discover strengths and weaknesses and offer recommendations based upon these findings.
Test anxiety can have a negative impact on a child's performance, so parents should attempt to take the stress off their child by making sure they understand that it is the effort and attention they give the test, not the final score, that matters. Parents can also ensure that their children are well-rested on the testing day and have a nutritious meal beforehand.
Norms —A fixed or ideal standard; a normative or mean score for a particular age group. Representative sample —A random sample of people that adequately represents the test-taking population in age, gender, race, and socioeconomic standing.
Alfred Binet and his colleague Theophile Simon first developed the work of measuring intelligence known as the Binet-Simon intelligence test. Today, the Binet-Simon intelligence scale is among the most important tests of intelligence.
Later, this Binet test was translated and revised by Lewis Terman, and this new edition is called the Stanford-Binet Intelligence test. In , the government of France appointed a committee with the task of identifying children who were performing badly in school and providing them with corrective education. This task led to the pioneering work of measuring intelligence. The committee included Alfred Binet , a French psychologist who played an important role in identifying the weaker children and identifying how to improve their performance through special training.
Binet and his colleague, another French psychologist, Theophile Simon developed the first scale in which was known as Binet-Simon Scale. This Binet-Simon intelligence scale or test is the father of the contemporary intelligent test after which several English language versions of the test were produced. The test contains thirty items, ranging from simple to complex to capture the ability of children of different ages. The test contained copying a drawing, repeating a string of digits, understanding a story, and so on.
They collected simple problems that measured higher mental processes such as reasoning, memory, and spatial thinking. The typical items required children to define common words What is a pencil? These items seemed to represent the ability level that was typical for children of a certain age, whereas other items are associated with those of different ages.
When the same question was given to seven and a year old children, it was passed by more than two-thirds of the children of seven and eight and less than two-thirds of the children that were younger than six. Mental age is the average age at which children achieve a particular score. A child with a chronological actual age of five who can answer questions of an eight-year-old level has a mental age of eight, in which case he is advanced three years.
A five-year-old who can answer the question expected for his age but not for higher ages has a mental age of five. View all related items in Oxford Reference ». Search for: 'Binet-Simon scale' in Oxford Reference ». All Rights Reserved.
