First is the value of knowledge, in the process of obtaining certification, they effectively improve their knowledge level and put them into practice, thus improve their experience level, in short they improve their personal productivity. Second, value of reputation, authentication is a relatively fair measure to the individual skill level, access to have the certification means that you have mastered certain skills.

The current situation is that too many people are only concerned about the value of reputation but ignore the value of knowledge.They regard the certification exam as an entry and think that with some kind of certification they can obtain certain level of salary or enter certain company. The idea and the corresponding actions directly lead to the devaluation of certification. Of course, in a particular period, having some kind of certification can immediately bring considerable economic returns but this needs special conditions such as manufacturers’ special policies and the relative scarcity of certification. To most of the certificates thus conditions are nonexistent and far-between.

With a purpose for economic returns, people would end up with disappointment. Many top technical certificates such as Network Appliance NS0-163 are not “once and for all”, and they will be continuously updated with the technology development, and also equipped with the corresponding replacement process.

That is to say, every two or three years, those who have the previous Network Appliance certifications must receive the subsequent trainings, inclusing a period of classroom learning, the latest technology presentation or taking part in relevent technology research groups, so as to ensure the effectiveness of technical certifications, otherwise the “gold-made” certification is just a piece of wasted paper. Certificate holders now demands a “composite certification”, if you hold more than one authentication certificates, such as holding both Network Appliance and NACA certification certificates, then your competitive advantage is obvious. However you should firstly be clear that which technique field you like and which technique you specialize in. If you neither like or specialize, you should never burden yourself.

Since most of the top technology certifications are high-end technology, besides training, it also needs several years of professional work experience for technical staff. And these certifications are with high difficulties inthemseves. According to survey, after one got some certificate the salary may improve in some certain degree: If you get NACA certification, the pay is on average increased by 40% -50%; if a Network Appliance NACA certification, the pay is increased by 40% – 60%.
