skills and knowledge certified by this examination represent a professional level of expertise for a certified
individual. The critical job activities of a Flex Developer are:
•
Recognize effective use and reuse of code in Adobe Flex programming for application develop-
ment, exception handling, troubleshooting, forms, and work with complex data types.
•
Recognize key concepts in database interactions, client state management, and data exchange.
Background and Experience
The test specification is intended to address the knowledge and skill areas that demonstrate competency as
an Adobe Flex Developer.
The knowledge level required is defined as having experience with non-code based software that uses
visual objects in development and the following general suggested prerequisites:
•
Two or more years experience with one or more programming languages.
•
Experience in the applied use of an enterprise-level database server.
•
One or more years of experience creating applications using Adobe Flex.
The Adobe instructor-led training courses that will assist in exam preparation are:
•
Adobe Flex 2: Developing Rich Internet Applications
•
Adobe Flex 2: Programming the Visual Experience
•
Adobe Flex 2: Creating Dashboard Applications
•
Using ActionScript 3 (final title TBD)
•
Advanced Adobe Flex Data Services 2 (final title TBD)
The skills and knowledge measured by this examination are derived from an understanding of the jobs of
current Adobe Flex Developers. A team of highly-qualified Adobe Flex developer experts defined the test
content and wrote the test items.

Note: This examination blueprint includes weighting, test objectives, and example content. Example
topics and concepts are included to clarify the test objectives; they should not be construed as a com-
prehensive listing of the content of this examination.
Exam Structure
The knowledge domains measured by this examination and the extent to which they are represented in the
examination are shown in the table below.
Response Limits
The examinee selects, from four (4) or more response options, the option(s) that best completes the state-
ment or answers the question. Distracters or wrong answers are response options that examinees with
incomplete knowledge or skill would likely choose, but are generally plausible responses fitting into the
content area defined by the test objective.
Test item formats used in this examination are:
Multiple-choice: The examinee selects one option that best answers the question or completes a statement.
Multiple-response: The examinee selects more than one option that best answers the question or com-
pletes a statement. The question will state how many options are correct; i.e., (Choose TWO).
Sample Directions: Read the statement or question and from the response options, select only the
option(s) that represent the most correct or best answer(s) given the information provided.
