in reply to Perl Certification

Certifications are only useful for admins and for some specific products.

Certifications for programming languages (even though some exists) are (IMHO) worth nothing at all.

I assume what you ultimately want is a job and not a wall decoration and what counts in the job-market above all is demonstratable experience.

These days it is simple to get experience even if you don't have a job - simply join an open-source project then you have something to show (far better than any certificate).
