How do ADHD accommodations differ from performance management?

This is a really valid concern, and the distinction matters. Accommodations are about access, not performance. They exist to remove barriers created by the environment so you can do your job on equal footing. Performance management, on the other hand, is about evaluating whether someone is meeting role expectations and addressing gaps in output or behaviour. Conceptually, accommodations assume competence. They start from the position that you can do the job, but certain conditions make it unnecessarily harder. Noise control, flexible deadlines, written instructions, or task prioritization support don’t lower standards. They change the conditions under which you meet them. Performance management frames difficulty as a deficit in skill, effort, or behaviour that needs correction. Accommodations frame difficulty as a mismatch between a person’s neurobiology and the environment. That’s a medical and legal distinction, not a personal one. Clinically, when we write accommodation letters, we’re careful to describe functional needs, not shortcomings. The focus is on what supports improve focus, accuracy, consistency, or regulation, not on what someone is doing wrong. It’s also important to know that accommodations are proactive. They’re meant to prevent problems, not respond to failure. You don’t have to underperform to deserve support. So if accommodations are being treated like performance management, that’s a misunderstanding of their purpose. They’re not a warning or a judgement. They’re a way to set you up to succeed in a system that wasn’t designed for your brain.
