OK, we could have added more suggestions to our list, from learning agile workflows to how effectively use GitHub, for example. However, too many options would only make your choice more difficult.

If you want to succeed and avoid having your new year’s resolutions wind up in your pile of shame (c’mon, we all have one!), be smart. Pick only a couple and focus on those. How can you make sure you choose the right ones for you? Bear with us. We’ve got the answer.

What Should You Consider When Choosing Your Software Development Training?

Online training, certifications, boot camps, YouTube videos, LinkedIn tutorials, you name it. The global software development market was valued at more than $461 billion in 2022 and is expected to rise up to 11.7% by 2030. Knowing this, it isn’t surprising that there are so many software developer courses available everywhere.

Want to ensure you pick the best software developer training for your needs without getting lost in the myriads of options available? Don’t forget to consider the following:

  • Format and schedule. Are you a traditional, in-person student, or an online training person? I’m the latter. I simply love online classes. Why? Because they’re highly flexible and always available. I can start and stop them when I want and where I want. This is great, above all when the course you chose requires a high number of hours to complete.
  • Instructor. Make sure you do your research about the course instructor before you pick your training. A few years ago, I attended a project management course in Germany. I do speak German fluently, but it’s not my mother tongue. The fact that the instructor was Swiss, made the course a bit more challenging. Don’t get me wrong, he was a skilled teacher and I loved his accent, but Swiss German is not what you learn at school. It’s definitely different from the German spoken in Germany and is harder to understand for a non-native speaker.
  • Paid or free? This will definitely depend primarily on your finances. Is your boss paying? You’re in luck. You’ll have a broader choice and you could opt for classes offered or sponsored by prestigious big tech companies (e.g., IBMGoogle), organizations (e.g., National Institute of Standards and Technology – NIST), and top universities (e.g., Princeton or Harvard). If your boss isn’t paying, don’t despair. Even if money is tight, there are many free or cheap platforms that, in some cases, offer courses or certifications (e.g., YouTubeUdemyCoursera, and the already mentioned LinkedIn).
  • Reviews and ratings. The innkeeper will always tell you that his wine is the best one. Want the truth? Check users’ reviews and ratings. It’s the best way to bet your hard-earned money on the right horse.
  • Prerequisites. In the majority of cases, you should be able to start the training without any previous knowledge, but this isn’t always possible, above all for highly technical courses.
  • Certificates. How would you prove to your employer that you have acquired a certain level of a specific skill? Either you show him practically (which may take some time and it isn’t really possible when you’re sending your job application) or you list your certificates. Not all software developer courses offer a certificate of completion, but if they do, it’d be a valuable addition to your resume, and LinkedIn profile.
  • Syllabus. Want to kill two birds with one stone and take your curriculum vitae to another level? Look for software developer training that includes hands-on projects. Why? Once completed, you’ll be able to add them to your list of achievements. Sometimes, they can even be useful in passing official certification exams.

So, which software developer courses and training are you going to add to your 2023 new year resolution list?
