Which is correct, access or assess?

Which is correct, access or assess, depends on meaning, both are correct English words but have different meanings and are often confused because they are homophones. Access means ability to enter, use, or obtain something, for example I have access to the building means I can enter building, or internet access means ability to use internet. It is noun and also verb meaning to retrieve, to access files. Assess means to evaluate, judge, or estimate value or quality of something, for example to assess risk means to evaluate risk, teacher assesses student performance means evaluates performance. So use access when talking about entry, permission, or ability to use, use assess when talking about evaluation or judgment. Spelling difference is double s at end for assess. Many people misspell access as acess with one s, which is incorrect. To remember, access has double c then single s, assess has single c then double s. If sentence is about entering building, system, or obtaining information, access is correct. If sentence is about evaluating, grading, or estimating, assess is correct. Both can be correct in different contexts.
