A conscientious person tries their best and does what's expected of them. They're responsible and care about details.
When people talk about someone being conscientious, they usually mean that this person is reliable, thorough, and pays attention to details. For example, if you work with a colleague who always double-checks her reports before submitting them, she might be described as conscientious. It's also common for employers to look for conscientious employees who will follow through on tasks and meet deadlines. A conscientious person is like the opposite of someone who tends to procrastinate or overlook important details - they stay focused and get things done.
Thorough, careful, or vigilant in one’s task performance.
