zend certification

Introduction:

Zend certifications have become an industry-wide standard and a measure of distinction that employers use to evaluate prospective employees.
Sponsored by Zend and developed according to American National Standards Institute (ANSI) standards, Zend Certification programs are designed to test a candidate’s level of knowledge in PHP  or Zend Framework without prejudice to other technologies. The tests use a set of testing questions that reflect real-world scenarios, including knowledge in many areas ranging from basics to the more complex topics. The certification exam is executed for Zend by Pearson Vue.

The exams are created by an Advisory Board made up of thought leaders in the PHP community. Because the exams are created with specific skills, knowledge and competencies that are matched to real-world job functions, Zend Certifications provide a measure of technical distinction that employers use to evaluate prospective employees.
