Web Application Developer Associate 10.2

Esri Certified Web Application Developer Associates are experienced in developing ArcGIS Web applications and are familiar with ArcGIS concepts.

This certification is for Web Developers who have performed tasks as part of a team, but do not yet have the experience required to define and lead major projects.

A qualified candidate for the Esri Web Application Developer Associate Certification will be familiar with ArcGIS concepts and be aware of performance considerations for building web applications. The candidate should be familiar with using object-oriented programming, as well as application documentation, maintenance, troubleshooting, and support.

A qualified candidate should be able to:

  • Identify ArcGIS geometry types, relationships, and operations
  • Define map and layer concepts and their applications in development
  • Understand relevant performance implications
  • Understand service configuration for out of the box services
  • Use services via REST and SOAP
  • Work with maps and layers, and other visualization elements
  • Use Web API tools
  • Work with secured services
  • Troubleshoot web applications
  • Deploy web applications
  • Work with items from ArcGIS platform such as web maps
  • Use services available from ArcGIS Server extensions such as network analysis, spatial analysis, and geoevent processor

The following list of skills measured is provided to familiarize candidates with topics covered on the exam and to help guide exam preparation. We recommend candidates review this list and assess their knowledge of each skill. Specific preparation resources are available to assist with refreshing in areas where any knowledge gaps are found.
