Gathering Quantitative Primary Data

In Video 7 of the CHES & MCHES certification prep series, we take an in-depth look at gathering quantitative primary data. This lesson falls under Area I — Assessment of Needs and Capacity, one of the core competency areas defined by the National Commission for Health Education Credentialing (NCHEC). Whether you are preparing for your initial CHES certification or advancing to the MCHES level, mastering this content is essential for exam success and professional practice.

In this video, we focus on how health educators gather quantitative primary data as part of the needs assessment process. Quantitative data gives you the numbers — the measurable, objective evidence that drives decision-making in health education planning. Understanding how to collect it properly is a key competency within Area I and a frequent topic on both the CHES and MCHES exams.

Area I of the NCHEC exam blueprint focuses on Assessment of Needs and Capacity. This competency area tests your ability to identify health education needs through data collection, stakeholder engagement, and community analysis. Health education specialists must demonstrate proficiency in both quantitative and qualitative assessment methods to design effective programs.

We walk through the most common methods for collecting quantitative primary data, discuss when each method is most appropriate, and connect it all back to how NCHEC frames these concepts in exam scenarios.

Understanding what quantitative primary data is and why it matters in health education is a key component of this competency area. The NCHEC expects certified health education specialists to demonstrate not only theoretical knowledge of this concept but also the ability to apply it in real-world public health scenarios. Understanding common collection methods including surveys, questionnaires, and biometric screenings is a key component of this competency area. The NCHEC expects certified health education specialists to demonstrate not only theoretical knowledge of this concept but also the ability to apply it in real-world public health scenarios.

This topic appears frequently on the CHES and MCHES certification exams. Scenario-based questions in this area often require you to identify the most appropriate course of action given a specific public health context. Pay close attention to the distinctions between similar concepts, as NCHEC exam writers frequently use closely related answer choices as distractors. Reviewing this material alongside practice questions will help reinforce your understanding and improve your test-taking confidence.

As you work through this content, consider how each concept connects to the broader health education process. The NCHEC exam blueprint emphasizes the integration of knowledge across all Areas of Responsibility. A strong candidate understands not only the individual competencies but also how assessment, planning, implementation, evaluation, advocacy, communication, leadership, and ethics work together in professional practice.
