Quality Control & SPC Basics Assessment

What this assesses

For quality inspectors and engineers who use control charts, capability indices, sampling plans and Pareto analysis on the shop floor. It covers 10 topics: cause and effect / 5 Whys; defects, DPU and DPMO; histograms and frequency; inspection and calibration; measures of centre and spread; Pareto analysis; process capability; sampling and acceptance; X-bar and R charts; and p-charts. The questions were drafted with AI and each one was checked in a separate evidence-based review; the paper is not independently expert-validated, so use it for learning and self-assessment.

Knowledge assessment. Objective questions with fixed answers, scored automatically. It shows what you know about the subject; it does not show that you can do the work hands-on.

AI-generated and AI-reviewed — not independently expert-validated. For learning and self-assessment only. Not a hiring, academic or professional qualification.

Before you buy

Prerequisites

No formal qualification is needed. Questions range from the basics to everyday working situations, so some study or hands-on experience of the topics listed will help.

What you receive

A report as soon as you submit, on the web and as a PDF: your overall result, a result for each skill with the number of questions behind it, strengths, development areas and a short development plan.

Certificate

A Certificate of Completion when you finish. A Certificate of Achievement only if GyaniX has set a passing standard for this assessment before you start and your attempt meets it; the page before you start says whether there is one. Practice attempts receive no certificate.

Retakes and practice

A retake is a new purchase and a new attempt. If most of the questions would repeat from your earlier attempt, this page tells you before you pay and offers a clearly labelled practice attempt instead.

Limitations

It is a knowledge assessment: it checks what you know through questions with clear answers. It cannot watch you work, so it is not proof of hands-on competence, and it is not a licence, an academic qualification or an accreditation.

Languages and content status

Available to take in: English. You choose the language before you start, and it stays the same for the whole attempt. If your language is not listed, the assessment is not offered in it yet; nothing is switched after you pay.

Questions were drafted with AI and checked one by one with evidence (code run, answers recomputed, sources opened). They have not been validated by an independent expert.
