Computational Mastery Exam General Information
This page is part of the practice exam only.
Expectations:
The Computational Mastery Exam is to address the following MTLE Basic Skills. Though there are
many other mathematics basic skills required, it is not reasonable to cover them all in a single
computational mastery exam.
MTLE Basic Skills: Mathematics
0011 Understand numbers and the number system.
demonstrating fluency in computation, including operations on decimals, percents, fractions, and exponents
using number sense and different number representations to solve mathematical and real-world problems
0014 Understand measurement concepts.
applying formulas to calculate perimeter, circumference, length, area, surface area, volume, and angles for
two- and three-dimensional figures in mathematical and real-world situations
Students should know basic fraction/percent equivalencies or be able to derive them. For example:

Passing Score:
Must meet all of the following requirements:
1. A comprehensive score of 25 or higher.
2. For each of the subcategories:
1–5: four or five correct.
6–18: ten or more correct.
19–23: four or five correct.
24–30: five or more correct.
If a student has obtained a perfect score in a subcategory and has not received a passing
score for the exam, then the student does not need to retake that subcategory when
retaking the exam.
