Acquia FE Specialist (D10) study guide
Acquia FE Specialist (D10) · Work through your exam, one topic at a time.
The Acquia Certified Front End Specialist - Drupal 10 Exam is a vendor certification credential aimed at front-end developers and themers who build Drupal 10 sites. It is intended for professionals who write and maintain a Drupal theme: template files, Twig markup, theme libraries, and the CSS and JavaScript that ship with them. Candidates typically come from agency or in-house teams where they own the look and feel of a Drupal site rather than its back-end configuration. Because the credential is front-end focused, preparation should center on how Drupal 10 renders pages: the theme layer, template and hook suggestions, Twig syntax and its Drupal-specific extensions, and the asset libraries that attach styles and scripts. The Acquia FE Specialist (D10) study guide has 5 sections and about 1,626 words.
01Fundamental Web Development Concepts
Expect questions on the request/response cycle, HTTP semantics, the DOM, CSS cascade and specificity, and JavaScript execution order. You should be comfortable describing how a browser turns HTML into a DOM, applies CSS via the cascade, and blocks rendering while parsing synchronous scripts.
320 words, about 2 min02Drupal Theming Fundamentals
This domain tests your mental model of the theme layer: theme discovery, the theme registry, template and hook suggestion resolution, base themes, libraries, and regions. You should be able to explain how Drupal decides which template file renders a given piece of output.
347 words, about 2 min03Twig Templating
Twig is Drupal's templating engine. Questions probe syntax, autoescaping, filters and functions, whitespace control, and the security model.
350 words, about 2 min04Theme Development Best Practices
This domain tests maintainability and correctness: preprocess functions, render arrays, caching metadata, template organization, and avoiding anti-patterns. Questions reward the approach that keeps logic out of templates and cacheability intact.
321 words, about 2 min05Front End Performance and Accessibility
Expect questions on asset loading strategy, caching, image optimization, Core Web Vitals, and WCAG-oriented markup. You should connect Drupal configuration (aggregation, lazy loading, responsive images) to measurable front-end outcomes.
