Gifted education (also known as Gifted and Talented Education (GATE), Talented and Gifted (TAG), or G/T) is a broad term for special practices, procedures, and theories used in the education of children who have been identified as gifted or talented.
The main approaches to gifted education are enrichment and acceleration. An enrichment program teaches additional, related material, but keeps the student progressing through the curriculum at the same rate. For example, after the gifted students have completed the normal work in the curriculum, an enrichment program might provide them with additional details about a subject in the curriculum. An acceleration program advances the student through the standard curriculum faster than normal. When gifted students have completed the normal work, they move on to the next level in the curriculum, even though the other kids of the class are still working on the first subject.
GATE tests usually consist of the three categories:
1. IQ Tests.
Individual IQ testing is usually the optimal method to identify the gifted children. The most popular tests are
Wechsler Preschool and Primary Scale of Intelligence（WPPSI-III)
Wechsler Intelligence Scale for Children IV (WISC IV)
Stanford Achievement Test.
2. Ability Tests
Usually school districts use the following tests to assess thousands of students:
Otis-Lennon School Ability Test (OSLAT)
Naglieri Non-Verbal Ability Test (NNAT)
Cognitive Abilities Test (CogAT)
According to Wiki, the Cognitive Abilities Test (CogAT) is a group-administered K–12 assessment intended to estimate student’s learned reasoning and problem solving abilities through a battery of verbal, quantitative, and nonverbal test items. The test purports purpose is to assess student’s acquired reasoning abilities while also predicting achievement scores when administered with the co-normed Iowa Tests. The author of the test is David F. Lohman, professor emeritus at the University of Iowa.
The Naglieri Nonverbal Ability Test (NNAT) is a nonverbal measure of general ability. There are three versions of this test, designed by Jack A. Naglieri and published by Pearson Education. The first is the Naglieri Nonverbal Ability Test – Individual Form published in 2004. The other two versions were published in 2007 and 2008, respectively. This includes the group administered Naglieri Nonverbal Ability Test – Second Edition and the Naglieri Nonverbal Ability Test – Online version. The most current version is NNAT2. Like all nonverbal ability tests, the NNAT is intended to assess cognitive ability independently of linguistic and cultural background.
The Otis–Lennon School Ability Test (OLSAT) is a test of abstract thinking and reasoning ability of children pre-K to 18. The Otis-Lennon is a group-administered (except preschool), multiple choice, taken with pencil and paper, measures verbal, quantitative, and spatial reasoning ability.
3. Achievement Tests
Achievement tests are usually given to the students in companion of ability tests such as CogAt. Typical Achievement Tests include：
Iowa Test of Basic Skills (ITBS)
Independent School Entrance Exam (ISEE)
The Iowa Test of Basic Skills (ITBS) is a series of standardized tests distributed by the College of Education of the University of Iowa (UI) aimed at assessing student achievement and progress from kindergarten through grade 8. Though the name seems to imply that this test is solely administered in Iowa, these tests are used throughout the United States to track student performance from early elementary school through junior high. Since the ITBS is an achievement test, it is important to practice for it.
