Question Format The test consists of a variety of short-answer
questions such as selected-response
questions, where you select one answer
choice or multiple answer choices (depending
on what the question asks for), questions
where you enter your answer in a text box,
and other types of questions. You can review
the possible question types in the Guide to
Taking a GACE Computer-delivered Test.
Number of Constructed-response Questions Test I: 0
Test II: 0
Combined Test I and Test II: 0
The GACE Biology assessment is designed to measure the professional knowledge of
prospective teachers of secondary school Biology in the state of Georgia.
This assessment includes two tests. You may take either test individually or the full assessment
in a single session. The testing time is the amount of time you will have to answer the questions
on the test. Test duration includes time for tutorials and directional screens that may be included
in the test.

The questions in this assessment assess both basic knowledge across content areas and the
ability to apply principles.
The total number of questions that are scored is typically smaller than the total number of
questions on the test. Most tests that contain selected-response questions also include
embedded pretest questions, which are not used in calculating your score. By including pretest
questions in the assessment, ETS is able to analyze actual test-taker performance on proposed
new questions and determine whether they should be included in future versions of the test.
Content Specifications
Each test in this assessment is organized into content subareas. Each subarea is further
defined by a set of objectives and their knowledge statements.
? The objectives broadly define what an entry-level educator in this field in Georgia public
schools should know and be able to do.
? The knowledge statements describe in greater detail the knowledge and skills eligible for
testing.
? Some tests also include content material at the evidence level. This content serves as
descriptors of what each knowledge statement encompasses.
See a breakdown of the subareas and objectives for the tests in this assessment on the
following pages.
