VS 2005 Certifications: TS Vs PRO

What to expect when you prepare for new Visual Studio 2005 Certifications??

By this time we all know that new certification strategy is divided into two major categories...
1.) Technology Specialization Series (TS)
2.) Professional Series (PRO)

Today I will dive deeper to give you an idea on what to expect in the exams and why such a strategy...

We always had enough technical weightage in the exams but there were still complains that certifications do not take care of everything needed to do a job... So we went further to understand what was missing in developer certifications... We got lot of intersting feedbacks...

The first result of those feedbacks was division of the certifications into TS and PRO... So what exactly does that division mean??... Here is the answer -
We tried to break our MS Technology Developer's skills into two major chunks; the first being pure technical skills and second being skills gathered from in job experiences...
So how are those different? The concept is easy to understand if you observe carefully... Technical knowledge about a particular technology can be gained by multiple ways, one of the ways can be experience in a job but that is not the only way... A person might know a lot about .Net Framework by reading books, MSDN, articles, taking e-Learning course, writing sample apps, technical presentations etc etc... These are some of the ways to learn more and start getting expertise in a technology... But many a times technical knowledge gained outside of practical experience may not have yet resulted into production code... Anyone who has written production code knows the difference between reading an article, writing sample code and writing actual production code... We also wanted to test that aspect of developers...

That is when we divided TS & PRO aspects of developers and finally MCTS and MCPD came into being... Well I am sure you got some idea but still I feel the concept can be made clearer so let us understand some more...
When you go to take TS exams, you should note that they will be based on a technology; When you go to take a PRO exam it will be based on a job role...
e.g. 70-528 .Net 2.0 web applications is a TS exam which focuses on ASP.Net 2.0 technologies whereas 70-547 Web Developer exam focuses on the industry job role of Web Developer...
A TS exam focues on "HOW TO?" do stuff with a technology where as a PRO exam tries to probe into "WHY? WHEN? and WHERE?" to do stuff with technology/s... Let's take an example to clarify:
"How to implement IDisposable interface in your class?" - This would be a TS question... but on the other hand "Why to implement or When to implement IDisposable interface in your type?" will be a PRO level question?


Now if you think about it you will realize that you can very easily read from a book how to implement IDisposable and probably follow and remember the steps to do so, but when it comes to finding out why your class really needs that implementation or are you going to break older versions by implementing IDisposable etc are the things that would be covered in the PRO exams...

So basically Why?, When? and Where? kind of scenarios whose answers are learnt from experience will be covered in PRO level developer exams... When you appear PRO exams you will probably see longer questions, you will probably have to synthesize like the way you would do while writing production worthy code, you might proably see lots of conditions and comapany policy rules which exist in real world, at times you might feel there are multiple correct answers (but read the question once more), you might find that the questions are tricky (but they probably would not be) etc etc... When you appear a TS exams things will be clear and simple, there will be definitive answers which you can predict and this is because of the very nature of these exams...

With this let us talk about how would you prepare for the TS and PRO Exams.. Before you go to appear TS exams you should know the technologies covered in the Exam in and out, there will be lot of prep material available for these exams... Before you go to appear PRO Exams you should have experience in developing applications with those technologies... There might not be a lot of prep material for these exams but then from the very nature of them there doesn't need to be a lot of material... You are expected to gain that knowledge with your expeirence and you proabably do not need to prepare that hard...

So do not get frustrated with the differences, understand them and go in prepared... In PRO exams you might have to understand all the moving parts of the scenario and only then you should answer a question... In TS you need to understand the technology well enough to answer...

Well, anyways I think this post is becoming too long and it is getting too late... We will talk about the rest later... In the meantime you can share your experiences of appearing PRO/TS exams here...
