The right certification training
Trainings vary a lot when it comes to quality. It's essential to choose your certification training provider based on things such as quality of materials, trainers' competence and skills, counseling facilities, track record etc. A good trainer is essential because you can learn from his real life's experience.
Usually, cost of training is a big issue for people, sometimes even a deciding factor. But price shouldn't be your only factor for choosing a certification training or institution. Always think about present and future opportunities and not costs involved to get there. It's not wise to save money by choosing an inferior training. But, remember that not always high cost means high quality.
Commitment and motivation
Keep in mind that best instructors in world or world class facilities cannot learn for you. You have to be committed to learning. Lack of commitment is a big problem and usually arises due to lack of motivation. In most of cases, this will 'help' you become one of those persons that pay training fee just to collect certificate. By becoming one of those persons, you just waste time and money. The certificate won't help you as much as knowledge gained during training through classes and exercises. So, keep in mind reasons you are there (this helps you stay motivated) and be prepared to learn and to apply what you have learned.
The right training model
Your skill and motivation level are two important factors that need to be take into consideration when choosing your certification training solution. Also consider financial constraints and available study time. All these factors are used to find right training model for you. Instructor-led trainings are considered most effective means of acquiring skills and knowledge, because they seem to achieve more for students than any other training options, especially when it comes to more difficult exercises. However, if you already have some practical skills and/or you don't have time to attend instructor-led training, other learning options are available to you (books, practice tests, computer based training and even online learning). If you find yourself in this situation, a blend of learning on your own and classroom learning might be right thing for you.
