What is this programme?
The WordPress Development Certificate from ecertificate.pro is an independent online program covering theme structure, child themes, custom fields, plugin security and site performance. Across roughly 24 hours of study you work through the template hierarchy, actions and filters, custom post types with sanitized meta, REST routes guarded by permission callbacks, nonce and capability checks, and query and caching repairs measured with Query Monitor and WP-CLI. Completion requires an online exam plus a practical build task, and the certificate is delivered inside your private panel on ecertificate.pro rather than as an email attachment. Every certificate carries a unique verification code that is checked only against the ecertificate.pro database; no other institution holds a copy of that record. This certificate is not government approved, is not accredited by any national or professional body, and it does not grant a license, a protected title, or any guarantee of employment.
Who it is for
Front-end and PHP developers moving into WordPress work, freelancers who maintain client sites, agency staff who inherit themes written by someone else, and site owners who want to stop breaking their theme with direct file edits.
What you will be able to do
- Map any URL to the exact template file WordPress will load, and split that template into reusable partials with get_template_part()
- Build a child theme that overrides parent templates and enqueues styles in the correct dependency order, so parent updates stay non-destructive
- Alter parent theme behaviour from outside it using add_filter(), remove_action() at the original priority, and your own extension points
- Register custom post types, taxonomies and meta fields with sanitize_callback, auth_callback and REST visibility set deliberately
- Ship a plugin with activation, deactivation and uninstall routines plus REST routes protected by a real permission_callback
- Apply nonce verification, capability checks, input sanitizing, late output escaping and $wpdb->prepare() to every form and endpoint you write
- Diagnose a slow site with Query Monitor, remove duplicate queries and autoloaded option bloat, and move repeated work into transients or a persistent object cache

How it works
Learning format
Self-paced written material, downloaded from your dashboard. No fixed schedule and no live sessions — you work through it when it suits you.
Material delivery
Everything appears in your dashboard as soon as your payment is confirmed. Files are served only to your signed-in session.
Prerequisites
Working PHP knowledge (functions, arrays, basic OOP) plus HTML, CSS and enough JavaScript to read a script. You should be able to run a local server, use a code editor and the command line, and move files over SFTP or Git. No prior WordPress API experience is assumed.
Completion
You work through the eight modules, then pass an online exam and submit one practical build: a child theme with a custom post type, a sanitized meta field, an escaped template output and a nonce-protected form. A passing result releases the certificate to your private panel.
Your certificate
Once your completion is confirmed, we prepare your certificate and upload it to your dashboard, normally within 24–48 hours. You receive an e-mail as soon as it is there — you never have to chase it.
Refunds
Because the material is delivered digitally and immediately, purchases are non-refundable once the files have been made available to your account. The full terms are in our Refund Policy.
