About the ISEE Upper Level
The ISEE Upper Level is the ACT of private school admissions for grades 9 through 12. Just as colleges use the SAT and ACT to determine applicant preparedness, many independent schools across the US achieve the same effect with the ISEE.
Because teachers, curriculums, and academic difficulty vary from school to school, a student’s report card is not sufficient enough to accurately compare students from different schools. Therefore they use a standardized test like the ISEE.
ISEE is an acronym that stands for the Independent School Entrance Exam. It is administered by the non-profit group ERB, Educational Records Bureau. You’ve probably heard of ERB before in the context of annual testing, particularly if your school administers the CTP-4, which is somewhat similar to the ISEE.

ISEE Math Review – Midpoint and Distance Formulas
The line graphs generated by linear equations are not limited to the portion of the graph shown, but instead continue on infinitely in either direction. Essentially, you are working with a segment of the line graph and a few of the points it contains. We can further analyze the measurements of these line segments through the midpoint formula and the distance formula: The midpoint formula measures the midpoint between two [...]
Math Review – Quadratic Equations and Their Graphs
Quadratic equations function in the same manner as linear equations in that you have a particular input resulting in a particular output. You plot points on the graph in the same manner as you do linear equations. The difference is that the graph of a quadratic forms a curved line, called a parabola, instead of a straight line. You will not need to know the quadratic formula for the ISEE. [...]
ISEE Math Review – Domain and Range
The set of all possible inputs for a function is called the domain, and the inputs fall on the x‐axis in a graph. The set of all possible outputs for a function is called the range, and the outputs fall on the y‐axis in a graph. If the domain has an input that is associated with (or results in) more than one output, then the relation between the inputs and [...]
ISEE Math Review – Function Notation
With so many formulas and equations to know and use, computations can become confusing when you must use several formulas and/or equations for the same problem. Function notation was developed to help differentiate between distinct equations and formulas, which are all considered functions. A function is a correspondence, or relation, between two sets of data where each input (one set of data) is associated with one output (second set of [...]
ISEE Math Review – Transformations of Functions
A transformation simply refers to moving the graph of a function around: If you want to move the line graph of y = 2x + 1 to the left or right, you increase or decrease the input. If you want to move the line graph of y = 2x + 1 up or down, you increase or decrease the output. Normally, the input of 2 for y = 2x + [...]
ISEE Math Review – Matrices
A collection of numbers (called entries) contained within a pair of [ ] brackets is called a matrix. A matrix is labeled by a variable, which is usually a capitalized letter. In a sense, matrices are like sets of data, except that a matrix is made up of rows and columns of data as opposed to just one row of data. A matrix is defined by the numbers of rows [...]
