Frequently Asked Questions
All three are international professional associations — LSSIAP and ILSSI from the UK, IASSC from the USA — and there is no geographic difference in the recognition of the certificates issued.
The key difference: IASSC introduced in March 2017 a 3-year validity period for all certificates issued. LSSIAP and ILSSI do not mention an expiry date on their certificates — unlimited validity.
This is unlikely, but in case of failure, the consequences depend on the type of certification chosen:
IASSC certifications: The examination fee must be paid again, according to the rates shown on iassc.org.
LSSIAP certifications: Within 6 months, you may retake the exam once at no additional cost. After that, a re-examination fee applies.
Upon your request by email or phone, Enviso sends a draft contract. After reviewing and signing the contract, an invoice is issued for the chosen course. Payment is due no later than the first day of the course.
