Sometimes, where the credential is unusual or foreign-issued. It is not worth it where the listing plainly requires a degree the applicant does not hold, because no evaluation creates one.
Spend on the gap you actually have
An evaluation is useful when the credential is genuine but hard to read: a foreign degree whose title translates awkwardly, an older Canadian credential whose name has changed, or a programme whose length is not obvious from the parchment. It is money wasted when the applicant's problem is that the listing requires a baccalaureate and he holds a diploma, because an evaluator's opinion that the diploma is comparable does not bind an officer. In that situation the same money is better spent on the licence application, on legal advice about a different classification, or on nothing at all until the employer has confirmed it will support a slower route. Check current government charges on the official fee schedule at the time of filing rather than budgeting from an older figure.
Hypothetical example: a graphic designer is asked to obtain an evaluation for a degree issued in French. The first review identifies whether the treaty entry accepts her credential and whether the document needs translation or a credential explanation. An original diploma, official transcript and certified translation settle those questions more directly than a costly report where the title is already unambiguous. She should ask the employer which charges it will reimburse before submitting anything. A dispute over reimbursement does not affect eligibility, but a reimbursement promise should be written down so it does not become a reason to rush an incomplete application.
