A+ Operating System Technologies

(2003) Examination Objectives

Effective November 26, 2003

Introduction

For A+ Certification, the examinee must pass both this examination and the A+ Core Hardware examination. The Operating System Technologies examination measures essential operating system competencies for an entry-level IT professional or PC service technician with the equivalent knowledge of at least 500 hours of hands-on experience in the lab or field.

CompTIA recently convened a core of A+ subject matter experts representing a diverse group of IT professionals, which resulted in the revised CompTIA A+ Operating System Technologies (2003) examination Objectives. The A+ Operating System Technologies exam will continue to validate that the successful candidate can demonstrate basic knowledge of operating systems (Windows 9x, Windows NT 4.0 Workstation, and Windows 2000). Additionally, the 2003 Objectives will cover later operating systems (Windows Me and Windows XP).

The skills and knowledge measured by this examination are derived from an industry-level and worldwide critical incident analysis, which was validated through a survey of almost 2,000 A+ certified professionals. The results of the survey are used in weighting the domains and ensuring that the weighting is representative of the relative importance of that content to the job requirements of an entry-level IT professional or PC service technician with the equivalent knowledge of at least 500 hours of hands-on experience in the lab or field. The intent is to certify individuals in a body of knowledge that is identified and accepted as the baseline or foundation of an entry-level IT professional or PC technician. It is not intended to measure ‘cutting edge’ technologies.

NOTE:

  1. • September 12th, 2003 CompTIA A+ exams in English will continue to test against the 2001 objectives in a conventional (linear, non-adaptive) format and will incorporate items against the 2003 objectives that do not count against the final score.
  2. • November 26, 2003 A+ exams in English test against the 2003 objectives and the 2001 objectives are retired.
  3. • This examination blueprint for the A+ Operating System Technologies examination includes the weighting, test objectives, and example content. Example topics and concepts are included to clarify the test objectives and should not be construed as a comprehensive listing of all the content of this examination.
