SAMPLE TEST QUESTIONS
The sample test questions in this document are designed to give you an introduction to the nature
of the questions included in the Washington Educator Skills Tests—Endorsements (WEST–E).
They represent the various types of questions you may expect to see on an actual test in this test
field; however, they are not designed to provide diagnostic information to help you identify specific
areas of individual strength or weakness or to predict your performance on the test as a whole.
Work through the sample questions carefully before referring to the answer key that follows. The
answer key provides the correct response for each question and lists the objective within the test
framework to which each question is linked. When you are finished with the sample questions, you
may wish to review the test objectives and descriptive statements provided in the test framework for
this test field.
In addition to reading and answering the sample questions, you should also utilize the following
preparation materials available on the WEST Web site:

Read WEST–E Test-Taking Strategies to understand how test questions are designed to
measure specific test objectives and to learn important test-taking strategies for the day of the
test.

Review the Test Summary and Framework for your test field to familiarize yourself with the
structure and content of the test. This document contains general testing information as well as
the percentage of the total test score derived from each content domain described in the test
framework.
A scientific calculator may be used for this test as needed in responding to the sample test
questions, and one will be provided at the test administration. Please refer to the current WEST
registration information regarding the use of calculators at the test administration.

Bowen's reaction series describes the order in which minerals form in a cooling magma, as shown above.
The plagioclase series on the right side of the diagram represents a continuous series of reactions that
occur as plagioclase minerals with different chemical compositions form within a cooling magma. The
left side of the diagram represents the discontinuous series of different minerals that form as the magma
cools. Olivine, the first mineral to form, reacts with the cooling magma to form a different mineral,
pyroxene. At each stage in this discontinuous series, the new mineral that forms as the magma cools can
replace the previous mineral.

1.
According to Bowen's reaction series, the
minerals in the discontinuous series react
with the magma to become different
minerals as the magma cools. Although
this was demonstrated experimentally in
the laboratory, some of the minerals that
form at higher temperatures have been
shown to survive as the magma cools.
Which of the following describes a
mechanism that allows some of these
minerals to be preserved as the magma
continues to cool?
A.
The magma becomes extremely
viscous, preventing chemical
alteration of existing minerals.
B.
The magma becomes so depleted of
mineral-forming elements that no
new minerals can form.
C.
The crystals that form first settle out
of the magma, becoming physically
separated from the magma.
D.
The crystals form in layers, allowing
their interiors to remain chemically
isolated from the magma.

Gold would likely crystalize under the
same conditions as which of the following
minerals of the Bowen's reaction series?

Bowen's reaction series, a magma with
which of the following compositions
