獲取A+證照，考生可以得到對認證知識的瞭解：全球有超過750,000的IT專業人員獲得了A+國際認證，全球知名的技術類公司包括聯想、HP、Dell、Ricoh、CompuCom要求他們的技術服務工程師必須持有 A+國際認證；A+ 國際認證被全球頂尖的IT企業組織所認可，包括Microsoft、HewlettPackard、Cisco、Novell等公司都將 A+ 國際認證納入其自身的認證體系。
“A+認證是全球範圍內公認的IT硬體維修技術能力認證標準，經聯想集團技術部門評估後證實，完全符合聯想集團對產品售後服務工程師技術認證的要求。”A+國際認證是電腦技術支援人員的行業標準。它是一種廠商中立的國際認證，是對技術人員完成例如安裝、預防性維護、網路安全和故障排除等工作的能力進行確認。通過A+國際認證的技術人員同時也具備良好的客戶服務以及與客戶溝通的技巧。
CompTIA Linux+認證計劃是最新進入Linux認證市場的。該計劃於2001年9月21日正式推出，目前已經在Linux從業人員和業內引起了廣泛的關注。幾乎所有的主要認證出版商都撰寫了針對Linux+認證的考試參考書，眾多的IT培訓中心都在準備Linux+認證計劃了。
同CompTIA推出的其他帶“+”號的認證一樣，Linux十資格證書只需要通過一場考試即可獲得（VUE和Prometric考試中心舉辦此類考試），一旦你獲得了Linux+資格證書，證書就終生有效。 Linux+考試價格是190美元，考試採用多選題形式，時長120分鐘，所覆蓋的內容很多都是和Sair以及LPI認證完全一樣的，但難度稍有降低。LPI和Sair認證計劃的考試對像是具有相當經驗的Linux網絡和系統管理員，而Linux+認證則主要面向只有半年左右的Linux體驗、想獲得基本Linux技術資格的個人。
CompTIA Security+ 國際認證是對安全領域專業人員知識的認定。安全領域是IT行業發展最快領域之一。CompTIA Security+ 認證是對系統安全、網路基礎結構、存取控制以及組織安全性等方面的知識進行考核。它是一種廠商中立的國際認證。
CompTIA Network+ 認證是對網路專業人士的知識和技能進行考核。它是一種廠商中立的國際認證，對於技術人員描述網路元件的特性和功能以及安裝、配置、檢查基本網路硬體、網路管理和網路安全能力進行驗證。
CompTIA A+ 國際認證是電腦技術支援人員的行業標準。它是一種廠商中立的國際認證，是對技術人員完成例如安裝、預防性維護、網路安全和故障排除等工作的能力進行確認。通過CompTIA A+ 國際認證的技術人員同時也具備良好的客戶服務和與客戶溝通的技巧。
CompTIA 為 IT 行業全球最大的廠商中立的 IT 認證考試開發機構。自 1993 年推出該認證項目以來，全球共有 90 多萬人通過了 CompTIA 認證考試。現在， CompTIA 還推出了其他認證考試專案，主要包括：PC 硬體認證考試專案、組網認證考試專案、伺服器認證考試專案、網際網路認證考試專案、電子商務認證考試專案、專案管理認證考試專案、培訓認證考試專案、Linux 認證考試專案、網路安全認證考試專案、家庭技術認證考試項目、文檔成像認證考試項目以及 RFID 認證考試項目。
CompTIA 認證是通過考試程式而獲得的一種資質證書，用於考核某一特定 IT 技術支援工作範圍內需要的知識。所有CompTIA考試均由命題專家開發。 CompTIA認證是廠商中立的國際認證，得到業界的廣泛認可。
獲得CompTIA認證的一些專業人士稱，他們對工作更有自信，工作品質也大為提高，同時客戶對他們的服務提出了更高的需求。許多員工也有同樣的感受。實際上，在考慮員工升職時，74% 的 IT 管理人員都認為 CompTIA 認證是一個重要考慮因素。 （更多…）
CompTIA 2011年規劃的新版本Security+ SY0-301將在2010年12月31日開始測試，CompTIA Security+認證是IT科技領域增長最快的資訊安全專業認證考試。現在嚴重安全威脅數量在增加，企業最需要IT安全專家計劃維持或增加其投資的安全性。 CompTIA的Security+是一個國際性的廠商中立的認證，拥有Security+認證可證明其能力：網絡基礎設施，訪問控制和安全管理。

A+ All in one certification exam guide (CompTIA) Michael Meyers 3rd+edition (Mcgraw Hill 2001)
The best A+ Certification guide in the field just got better.
Because, let’s face it; in terms of walking you through the computer from the ground up, there wasn’t anything better out there. Other A+ guides will fling random tables of processors and numbers at you as if you were a dartboard, hoping that maybe a couple of facts will stick; Michael Meyers’s All-In-One A+ Certification Exam Guide starts by showing you the same sets of problems that faced the original designers of the PC. You have just designed a chip that can handle thousands of calculations per second. Now how do you talk to it? How do you get other components to communicate with it? How do you know when it’s listening?
By the time you finished the previous editions, you knew all of the answers–and better than that, you understood why the hundreds of processor types were so hinky. You had been faced with the same hurdles that the designers had to face, and you’d had the solutions explained to you–all in a delightful, easy-to-digest format. And furthermore, you’d had that same treatment given to every part of the PC, from the monitor all the way down to the motherboard. If you got confused, a wealth of pictures would show you the difference between an RJ-45 and an RJ-11 jack.
The only problem was that it was a little out of date, but you could forgive it for that. Everything else was so amazingly strong, and the A+ exam itself tends to be a little behind the technology curve anyway–so it was a forgivable sin.
Sin no more, my friends, and read on–the latest edition of this book isn’t quite cutting edge, but it deals with Windows 2000, 3-D video cards, surround sound speakers, and burnable CDs. You might not find all of these listed on the A+ exam, but there they are nonetheless.
Which is, come to think of it, another strength of this book: It goes beyond the normal testable topics and really wants you to know what problems you’re likely to face as an actual technician in the real world. Meyers gives lots of hands-on advice, frankly admitting that this topic is still tested but he’s not quite sure why, telling you that power supplies can be repaired (and should be) even if the test says otherwise, and generally giving copious examples from his tech experience to show “what can go wrong.”
In fact, if a major criticism can be leveled at this book nowadays, it’s that it might go a bit too in-depth at times; Meyers’s zeal to show you everything he knows about computers makes it possible to get lost in the wealth of information and not focus on critically-tested subjects. But keep in mind that if you truly understand even 60 percent of this book, you’ll pass the exam with flying colors–it’s that good.
The book has ten questions at the end of every chapter that aren’t modeled specifically after the A+ exam, but they are fairly tough questions nonetheless. There’s also a CD that has the standard array of video clips and test questions, but it also has several tech utilities that Meyers himself recommends–a great value.
In short, this is simply one of the best test-prep books on the market for any exam, and it’s also one of the few books that’s completely honest: It is, when it comes down to it, an all-in-one guide. Buy this and you will pass. Highly recommended. –William Steinmetz
