Engineering principles and assessment criteria
Human Impact Certified rewards intelligent engineering decisions.
The standard defines measurable engineering practices for websites that deliver exceptional digital experiences while minimising unnecessary resource consumption.
It is technology-neutral. Certification evaluates outcomes—not platforms, vendors, frameworks or programming languages.
Defining principle
Human Impact Certified rewards intelligent engineering decisions that achieve more while consuming fewer digital resources.
The five pillars
No strength in one discipline should conceal weakness in another.
Pillar 01
ObjectiveDeliver information to users as quickly and efficiently as practical.
Performance is the efficient delivery of digital information. It affects satisfaction, accessibility, business outcomes and resource consumption.
Every unnecessary byte should justify its existence.
Assessment areas
Pillar 02
ObjectiveEnsure every person can successfully access and interact with digital information.
A website that excludes users cannot be considered fully optimised. Accessibility is fundamental engineering, not a finishing layer.
The web belongs to everyone.
Assessment areas
Pillar 03
ObjectiveReduce unnecessary digital resource consumption.
Every webpage requires bandwidth, processing, storage and energy. Intelligent engineering reduces these demands without limiting innovation.
Move more information with fewer resources.
Assessment areas
Pillar 04
ObjectiveReward robust, maintainable and resilient engineering.
High-quality engineering improves reliability, security and long-term maintainability while reducing future development effort.
Engineering quality compounds over time.
Assessment areas
Pillar 05
ObjectiveEnsure information can be understood efficiently by intelligent systems.
Well-structured websites improve discoverability and machine understanding. Engineering for AI should strengthen—not compromise—the human experience.
If information is easier to understand, everyone benefits.
Assessment areas
Technology neutrality
A website built with WordPress, static HTML, a JavaScript framework, a proprietary platform or a future technology may qualify when it satisfies the published outcomes of the standard.
Innovation is encouraged. Vendor preference is not.
The Human Impact test
When the answer is yes, it belongs in the standard.
Exceptional websites are not defined by how much technology they use. They are defined by how intelligently they use it.
