About the Exam

  • Exam Name: Acquia Certified Back End Specialist - Drupal 9

The purpose of this exam is to validate the skills and knowledge of a Drupal Developer in the area of Back end Development (Coding). This exam is based on the Drupal 9 platform.

This exam can be taken in a testing center or in your office, provided certain environmental details can be guaranteed (such as a webcam on the testing computer). Do not be discouraged if you do not pass the exam the first time. Many do not.

This exam validates a candidate’s ability to:

  • Design, develop and deploy Drupal 9 based solutions focusing on back end topics
  • Understand the core Drupal 9 basic architecture and best practices for site building and code development
  • Develop and implement new Drupal 9 modules
  • Customize and extend existing Drupal 9 modules

The basic knowledge and skills required include the following areas and objective components:

  • Professional experience using Drupal 9 technology
  • Setup and configuration of Drupal 9 sites
  • Developing new or customizing existing modules
  • Knowledge in HTML, CSS, JavaScript/JQuery, and Object Oriented PHP

Steps to Specialist Certification

Take Introductory Drupal Courses

Customers can access Drupal preparatory courses on Acquia Academy at https://customers.acquiaacademy.com/learn for free, and review them as many times as you like. If you are in an Acquia workshop or training program, you may be assigned the courses that you need to complete to obtain your certification.

Public, instructor-led Drupal training is available for purchase by the seat, and private training is available for purchase for groups of up to 10 people. Visit Acquia Professional Services Product Guide to review our available public and private Drupal training.

For Back End Specialists, we offer the following to get you started on your Drupal journey:

  • Drupal Site Building
  • Drupal Layout and Theming
  • Drupal Module Development

After taking the courses, build a small website on your own to reinforce the concepts learned in the course.

Gain Practical Experience

Completing the courses may not fully prepare you to take the certification exam. You need some practical experience to attempt the exam. We recommend that you gain practical experience by working on at least 2-3 real-life projects.

Perform Self-Assessment

Once you decide to take the exam, we recommend that you study the domains and topics covered by the exam and their relative weight. You should also perform a Self Assessment of your own areas of strength and weakness vis-a-vis the domains/topics covered by the exam blueprint. This is a recommended starting point for experienced Drupal back end developers.

Use Labs and Study Guide

Based on your self-assessment, you may need to gain knowledge and experience in some domains or topics. The best way to learn Drupal is by working or experimenting with it. Follow the suggestions given for preparation in the Preparation section and refer the external resources given in the Study Guide section.

Note

This exam blueprint includes topics /domains and test objectives to help guide the test taker. They should not be construed as a comprehensive listing of all of the content of this examination.

Self-Assessment

Experienced Drupalists will likely know their weaknesses more than they know their strengths. You might have judged your own skill levels while reading through the domains listed above. It is quite natural for you to be more experienced and proficient in one domain than another. Also, within a domain, it is quite likely that you have hands-on experience on some topics but have never touched other areas within the same domain.

How to Use Self-Assessment

We suggest you perform a skills and expertise self-analysis with respect to the domains and topics listed in the blueprint. The blueprint lists test objectives (topics) for each domain. Rank your skills on a scale of 0 to 10 against each test objective (0 for absolutely zero knowledge or exposure and 10 for complete mastery).

  • Topics with 8+ score are your strengths.
  • Topics with a score of 5 to 7 will need some preparation.
  • The ones below 5 may require a lot of preparation, or guided instruction.

You may use the following table to carry out your evaluation.

Preparation

Once you have a list of topics for which you need preparation, you will possibly face two challenges:

  1. Find and study documentation and knowledge resources for the topics.
  2. Find enough practical case studies covering the topics.

Knowledge Resources

Supplementing introductory Drupal training with documentation and online resources is a good idea.

We provide a list of online resources and documentation for each learning domain in the Study Guide section of this document.

Labs / Case Studies

The second challenge of finding enough practical case studies covering the topics is likely to be more daunting. Here are a few ideas and suggestions for finding finding case studies for your preparation:

Back end development

If you have not worked on backend development or module development, preparing for this part of the exam could appear to be a challenging task. In this case, studying the code of modules developed by your team may or may not help, as modules developed could either be extremely complex or very specific to the requirement or use case. The exam expects that you have an overall understanding of Drupal’s API, core plugin system, and their applications.

We suggest that you attend a module development course and/or build a small module on your own to prepare for this domain. If you cannot attend a training program and are a self-learner, you may try the Examples Module (https://drupal.org/project/examples.)

Examples module provides highly documented working code snippets for many of the Drupal APIs and concepts covered under the blueprint of this exam.

Study Guide

Tools to Know for Drupal Development

Drupal Coding Standards

An overview of coding best practices and standards as they are applied in the Drupal community can be found here.

These coding standards, detailed for every area in which code might be produced during Drupal development, represent the broadly established best practices of the community. Adhering to these best practices will make development go more smoothly, and your contributions to Drupal core or modules to be more readily and easily accepted. If you are working on a project with Acquia technical support, these are the coding standards to which pull requests must adhere.
