Expert writing Tips

Best practice

When using "have been proficient", clearly specify the area of proficiency to provide context and avoid ambiguity. For example, "They have been proficient in data analysis for several years" is more effective than "They have been proficient."

Common error

Avoid using "have been proficient" without specifying the skill or area of expertise. Saying someone is simply "proficient" lacks clarity and impact. Always provide context to showcase the specific competence.
