Best certifications to get

Best certifications to get

Some people regard certifications as overrated. But given the number of resumes human resources departments get, having the certifications listed in the job description, even if the description calls them desirable and not required, really helps. You need something to make you stand out, and certifications are an effective way to do that. Here are the 16 best certifications to get, in my 20 years of experience in IT.

If you already have an IT position but don’t have some of these certifications, these certifications can be good goals to put on your annual review. Most of them are attainable within a year, and they increase your value to your present employer, so a good employer is willing to pay for the training and examination fee as long as you agree not to leave within a certain period of time.

Also, there’s no reason to think you need to get all of these. You can have a long and productive career with one or two of them. The key is which two. But you’ll know which ones apply to your situation and which ones don’t. Like a college degree, having certifications opens doors. If you don’t have a degree, certifications can help make up for it.
