Quantity Discrimination Overview
The Quantity Discrimination-Least assessment assesses a student's ability to select the smallest of four visually presented numerals between one and ten. For the 30-second administration, the examiner shows the student four numerals and asks, "Which is least?" The resulting score is "1" if the student correctly points to or says the correct numeral/number. The final score is prorated from the number of items responded to correctly in 30 seconds to the total correct in 60 seconds.
Quantity Discrimination-Least is designed for screening and progress monitoring.
This measure is available in Braille.
Thirty unique 4 x 1 rows of numbers were created for the Quantity Discrimination assessments, 15 are used for the “Which is most?” questions, and 15 are used for the “Which is least?” questions. There are four items shown on each page. There are four non-repeating numerals between 1 and 10 in each row. The numerals were placed randomly in each row, and the correct answer is never in the same position in the row more than one consecutive time. For example, if the correct answer to item 1 is in the first numeral in the row, item 2’s correct answer would not be placed in the same position. Prior to the start of each assessment, students are provided with two practice items and are instructed to move as quickly as they can through the items. The practice items are displayed in the same format as test items and are intended to familiarize students with the objective of the task.
