A+ Core Service Technician Examination Blueprint
Version 7/17/98

These test objectives will be available to test on through March 30, 2001.

Introduction

For A+ Certification, the examinee must pass both this examination and the A+ DOS/Windows Service Technician examination. This examination measures essential competencies for a break/fix microcomputer hardware service technician with six months of on-the-job experience. The examinee must demonstrate knowledge to properly install, configure, upgrade, troubleshoot and repair microcomputer hardware. This includes basic knowledge of desktop and portable systems, basic networking concepts, and printers. The examinee must also demonstrate knowledge of safety and common preventive maintenance procedures.The skills and knowledge measured by this examination are derived from an industry-wide job task analysis and validated through a worldwide survey of 5,000 A+ Certified professionals. The results of the worldwide survey were used in weighting the domains and ensuring that the weighting is representative of the relative importance of that content to the job requirements of a service technician with six months on-the-job experience. 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 comprehensive listing of the content of this examination. The table below lists the domains measured by this examination and the approximate extent to which they are represented.

Domain % of Examination
(approximately)
1.0 Installation, Configuration, and Upgrading 30 %
2.0 Diagnosing and Troubleshooting 20 %
3.0 Safety and Preventive Maintenance 10 %
4.0 Motherboard/Processors/Memory 10 %
5.0 Printers 10 %
6.0 Portable Systems 5 %
7.0 Basic Networking 5 %
8.0 Customer Satisfaction 10 % 1
Total 100.00%

Note: For the A+ tests in the conventional format, which are available in French, German, Spanish and Japanese only. The Customer Satisfaction domain will be scored but will not impact final pass/fail score on the A+ Core examination. For the English adaptive test, there are no customer satisfaction questions. The 10% previously focused on customer satisfaction has now been divided equally among the other 7 content areas.
