Salesforce.com does a good job of defining certification paths and encouraging people to become certified.
Salesforce ecosystem is complex and there is something for everyone to do. Naturally, their certifications have evolved into different paths including –
- Marketing Specialist
- .. and a host of others
Each path has a series of exams that you can attend to advance further in knowledge (and possibly in your career). See more details on the various certification paths from Trailhead. Or, see our own free study guide for becoming Salesforce Developer certified.
Visualforce was the default customisable UI in Salesforce for years. When that gave away to Lightning Aura, and later on, Lightning Web Components, something remarkable happend.
- It became easier to find talent since developers can now adopt quickly to Salesforce way of doing things (we are still talking about the frontend development here)
- The ecosystem became standardized to Industry practices
- The new architecture is component-based, application-centric and is more productive (subjective?), easier to reuse and maintain
As I understand the certification is intended at two kinds of developers –
Part 1: Get LWC Specialist super badge
Complete this super badge called “Lightning Web Components Specialist” targeted at developers who are interested in frontend development.
Super badges are fun (but also sometimes scary). Regardless it is quite an involved process – you are expected to complete a number of courses on Trailhead that culminate in a project. You get to not only implement what you learnt in the project, but can also have this effect of seeding a level of doubt in your capabilities.
This part is like an open-book test. You can take your own time to complete the individual courses and to do the project. You will be evaluated by a tool to determine whether you can enter the elite club of LWC specialists. No real humans, other than yourself, are involved in this process.
Part 2: Attend an exam
You have to attend this exam online or in an exam center (the latter cannot happen in 2020).
- Content: 60 multiple-choice/multiple-select questions ( with 5 non-scored questions)
- Time: 105 minutes
- Registration fee: $200 (Re-take fee: $100)
You will once again get evaluated by our computer overlords to admit you to the club.
