The Talend Data Integration Certified Developer Using Talend Studio exam, run by Qlik under the TDICDTS code, costs USD 250 and earns that back only if Talend Studio is part of the work you actually do. It is a hands-on developer exam, not a management overview, and what you get out of it depends on how closely the ten syllabus topics match your day-to-day job. This guide explains what the exam covers, who should sit it, what the real cost looks like, how the ten objective areas break down, and how to prepare for it in six weeks.
If the exam is already on your calendar, the Talend Data Integration Developer practice exam on AnalyticsExam matches the same 55-question, 90-minute exam, with practice items built around the ten objective areas below. What follows is about that decision: who the credential actually pays off for, and what passing it takes.

What does the Talend Data Integration Developer certification actually prove?
It proves you can build, test and maintain Talend Studio jobs to a professional standard, not just describe data integration in general terms. Qlik, which folded Talend into its own certification programme after acquiring the company, pitches the TDICDTS exam squarely at developers who already work inside Talend Studio day to day, not at architects or managers who only read the diagrams.
