ExploreAbout this exam
PCED – Certified Entry-Level Data Analyst with Python is an entry-level Python Institute certification (exam code PCED-30-02, active since July 15, 2025) that confirms foundational knowledge of data analytics and Python programming. It is aimed at complete beginners, aspiring data analysts, students and career changers, professionals in non-technical roles, and educators who want a structured first credential in data work. The exam covers data collection fundamentals; organizing and cleaning data; transformation and analysis with built-in Python features and essential libraries (csv, math, statistics, datetime, collections, NumPy); drawing basic insights and communicating them through text-based summaries and basic charts; and data ethics, visualization, and storytelling concepts. Built-ins such as variables, data structures, file handling, control flow, and functions run through the whole syllabus. There are no formal prerequisites, though the Institute recommends PCEP-level knowledge plus a foundation in mathematics and statistics. The exam lasts 60 minutes plus an NDA, contains 40 single- and multiple-select and scenario-based questions, is delivered in English and Spanish through TestNow™, costs from $69, and requires 75% to pass; the credential is valid for 7 years. Preparation typically combines the Python for Data Analytics 101 (PD101) course, the published PCED syllabus, and the official practice tests, which let you rehearse the question style before booking.
What you'll study
About PCED preparation
What is the exam format and how long do I have?
You get 60 minutes of testing time plus an NDA to accept first. There are 40 questions, mixing single-select and multiple-select items with scenario-based questions built around small datasets. Delivery is through the OpenEDG Testing Service – TestNow™ platform, and the exam is offered in English and Spanish.
How hard is PCED for someone with no data background?
It is deliberately an entry-level exam: the Institute describes it as designed for beginners with no or very little prior experience in data analysis or programming. The difficulty comes from breadth rather than depth - you need comfortable, accurate use of core Python plus modules like csv, statistics, datetime, collections, and NumPy at a basic level.
What score do I need, and what happens if I fail?
The passing score is 75%. If you fail, you must wait 7 days from your last attempt before retaking. With a voucher that includes a free retake, after the waiting period you open Exam History in your Test Candidate account and click Get Free Retake. With a single-shot voucher, you must buy a new voucher.
What does the exam cost and what bundles exist?
The exam starts from $69. Bundles listed by the Institute are Exam + Retake from $86 and Exam + Retake + Practice Test from $95. A standalone practice test is $29. Prices are quoted as 'from' figures, so confirm the current amount in the OpenEDG Voucher Store before purchasing.
Do I need PCEP before taking PCED?
No formal prerequisites exist. The Institute's recommended experience is PCEP™ or equivalent knowledge plus a foundation in mathematics and statistics. If Python syntax, lists, dictionaries, loops, and functions are already familiar, you can go straight to data-specific practice; otherwise start with Python Essentials 1 and 2 first.
How should I order my study plan?
Work through the published PCED syllabus domain by domain, using Python for Data Analytics 101 (PD101) as the guided course. Practise reading and cleaning a CSV with the csv module, computing means and medians with statistics, formatting dates with datetime, counting with collections, and doing simple array math in NumPy. Finish with the official practice tests under timed conditions.
What are the most common ways candidates lose points?
Typical slips: confusing module functions with built-ins, mishandling file opening and closing, misreading multiple-select items and choosing only one option, and mixing up when to use mean versus median on skewed data. Scenario questions also punish candidates who ignore the stated business question and jump to code details.
How long is the certification valid, and what comes next?
PCED is valid for 7 years. Within 24 hours of passing you receive a link to your digital certificate, a verification code, and a Credly Acclaim badge. The natural next step is PCAD™ – Certified Associate Data Analyst with Python, which covers more advanced techniques and tools.
Can I take a practice test before the real exam?
Yes. PCED-30-02 practice tests are sold in the OpenEDG Store at $29, or bundled with the exam. Buy the practice voucher, log in to your OpenEDG Learner Account, switch your role to Learner if needed, open Practice, enter the voucher code, accept the terms, and activate it.
