The ACD301 exam is Appian's official test for the Lead Developer credential, a certification at the Senior / Lead level. Earning it tells employers your skills have been verified by the vendor itself, which carries real weight in hiring and promotion decisions. Within the same certification track, it sits alongside Appian Certified Associate Developer (ACA), Appian Certified Professional Developer, so it can also serve as a stepping stone toward those credentials.
Appian divides the Appian Lead Developer exam into 6 domains. The largest ones are Appian Platform Fundamentals at 10%, Data & Integration at 20%, Process Design & Modeling at 20% — together these account for the bulk of your score, so start there. The complete domain-by-domain outline appears in the exam topics section above on this page.
Two layers of protection here. First, delivery: your ACD301 product is available for instant download, and a copy lands in your email within one minute of payment — if 2 hours pass with nothing (check spam first), our support team will resend it. There is no cap on how many computers you can install it on. Second, the refund policy: if you take the ACD301 exam within 60 days of purchase and fail, you may claim a full refund. The claim needs a scanned enrollment slip plus your official Score Report PDF, filed within 2 days after the exam, and it is settled within 7 days. The policy covers only the corresponding exam — attempts within 3 days of purchase, exams never actually taken, free materials, and expired orders are excluded, and the candidate's name must match the payer's. If you would rather keep studying, you can instead exchange your product for two free exam products of equal value and keep the update service on your original purchase.
You will face 80 questions in 120 minutes on the Appian Lead Developer exam. Do the math and the per-question budget is tight, which is why pacing drills matter as much as content review. Our advice: take two or three full timed mocks in the BraindumpQuiz engine before the real thing, and practice skipping a stubborn question instead of burning five minutes on it.
Of course. BraindumpQuiz publishes a free PDF demo for the Appian Lead Developer exam so you can review real sample questions and answers first. Every purchase also includes 365 days of free updates, and after that period you can renew the update service at a 50% discount directly from your member zone.
Recommended: 1-2 years Appian development experience; Associate Developer certification preferred but not required Eligibility rules are set by Appian and do change from time to time, so double-check the latest requirements on the official exam page at https://academy.appian.com/certification before you register.
