Brainbench offers a wide range of skills assesments for which you can receive a Brainbench certification. The tests run the gamut from listening skills, to anatomy, to programming, to C++. Based on your performance on each exam you will get either a Brainbench Certification or Master Certification. Brainbench then maintains an online transcript of your certifications, which you have the option of making public so that others can view your results. You can also add non-Brainbench certs to the transcript if you would like to maintain a full transcript of your certifications.Certification Preparation
Aside from providing actual Brainbench certifications, there are also tests which are aimed directly at certification preparation for those studying for Java, Cisco, MCP, Unix, and other vendor sponsored certs. All of the certification preparation exams cost $25 each or are available with the subscription. The exams are thorough and although they are open-book (obviously), if you can complete one without assistance from reference materials, you can consider yourself prepared for the vendor exams.I went in and took three of the free exams and am considering getting the BCIP (Brainbench Certified Internet Professional). In fact, one of my free exams already counts toward the BCIP Web Designer cert.
One quick warning, if you are a exam or cert junkie, the free exams can be addictive! Overall, with it's credibility, affordable prices, and great exams, Brainbench is definitely worth considering as a standalone cert or as a training resource.
