In the tech industry, one day a skill is hot, the next it’s not. IT professionals spend a lot of their career learning, training, and trying to keep up.

Job-hunting site Dice prides itself on helping IT pros navigate which skills to pursue. It just concluded an analysis of its database of 80,000-plus tech jobs from April 2015 through April 2016 to determine the fastest-growing skills based on job openings.

We then crosschecked those skills against Dice’s annual-salary survey, published in February, which offered the average salary for jobs using those particular skills in 2015.

The good news? All of them are part of jobs that command average salaries of over $110,000.
