Acquia Developer (D10) study guide
Acquia Developer (D10) · Work through your exam, one topic at a time.
The Acquia Certified Drupal 10 Developer credential is a professional certification aimed at developers who build and maintain Drupal 10 sites and who want independent, third-party validation of their skills. It is intended for working developers - typically those with hands-on experience writing custom modules and themes and configuring Drupal site architecture - rather than for beginners or for purely editorial users. Because the exam is built around Drupal 10 specifically, preparation should focus on Drupal 10 APIs and conventions rather than older versions. The published blueprint groups the material into five weighted areas: Drupal fundamentals and site building (20%), module and theme development (25%), Drupal APIs and data modeling (25%), performance, caching and security (15%), and the Acquia platform and deployment workflow (15%). The Acquia Developer (D10) study guide has 5 sections and about 1,682 words.
01Drupal Fundamentals and Site Building
Drupal 10 separates configuration (content types, fields, views, display modes, roles) from content (nodes, terms, users). Configuration is exportable YAML; content lives in the database.
360 words, about 2 min02Module and Theme Development
A custom module needs an .info.yml file with name , type: module , and core version requirement . Drupal 10 uses PSR-4 autoloading: src/ maps to the module namespace.
341 words, about 2 min03Drupal APIs and Data Modeling
Entities are defined by annotations or PHP attributes and stored via the Entity API. Field types (string, text, entity reference, datetime) map to storage.
319 words, about 2 min04Performance, Caching, and Security
Drupal's render pipeline is cacheable: render arrays carry #cache with keys , contexts , and tags . Cache contexts vary output (e.g., user.roles , url.path ); cache tags invalidate (e.g., node:5 , config:system.site ); max-age sets lifetime.

Acquia Cloud provides environments (dev, stage, prod) on a subscription. Code flows via Git (or pipelines) from a repository; each environment has a branch.
