Most PHR candidates can list Kirkpatrick's four levels of evaluation. But many fail to connect Level 2 (Learning) to Level 4 (Results) with a credible ROI, which is exactly what the exam demands. They know the what, but not the why or the how much. This gap between knowing a term and applying it to a business case is where points are lost.
The PHR Learning & Development cheat sheet covers essential formulas like Training ROI, frameworks like ADDIE and Kirkpatrick's Levels, adult learning theories (Andragogy), and key legal rules (ADA, Title VII). It focuses on application, helping you master needs analysis, program evaluation, and career development concepts for the 2026 exam.

What Are the Core L&D Formulas and Frameworks?
The Learning and Development (L&D) section demands you think like a business partner, not just a training coordinator. Success hinges on your grasp of several core quantitative and qualitative frameworks. These are the tools HR professionals use to justify investments and demonstrate value. You need to know the formulas, but more importantly, understand what each component represents.

Training ROI Formula
The Return on Investment (ROI) for training is the single most important metric for showing the financial benefit of an L&D program relative to its cost.
🧮 Formula: ROI = (Monetary Benefits − Training Costs) ÷ Training Costs × 100%
- Monetary Benefits: Quantifiable gains from the training, such as increased productivity, reduced errors, higher sales, or lower turnover costs.
- Training Costs: All direct and indirect expenses, including instructor fees, materials, facility rentals, and participant wages during training.
- Identify Monetary Benefits: $100,000
- Identify Training Costs: $25,000
- Apply the ROI Formula: ($100,000 − $25,000) ÷ $25,000 × 100%
- Result: ($75,000 ÷ $25,000) × 100% = 3 × 100% = 300%
This 300% ROI means for every dollar invested in the training, the company gained three dollars in return.
Kirkpatrick's Four Levels of Evaluation
This framework provides a structured approach to assessing training effectiveness. You must know the order and what each level measures.
| Level | What it Measures | Method Examples |
|---|---|---|
| 1. Reaction | Participant satisfaction with the training. | Surveys, smile sheets, feedback forms. |
| 2. Learning | Increase in knowledge, skills, or attitudes. | Quizzes, tests, skill demonstrations. |
| 3. Behavior | Transfer of learned skills to the job. | Observation, performance appraisals. |
| 4. Results | Impact on business outcomes. | ROI, productivity, sales, turnover rates. |
The ADDIE Model
ADDIE is a sequential process model used by instructional designers. Understanding each phase is key to answering questions about building a training program from scratch.
- Step 1: Analysis: Identify the performance gap, target audience, and learning objectives. Answers "What is the need?"
- Step 2: Design: Outline learning objectives, assessment instruments, exercises, and content. Answers "How will we meet the need?"
- Step 3: Development: Create the actual learning materials and activities. Answers "What will the training look like?"
- Step 4: Implementation: Deliver the training program to the target audience. Answers "How will we deliver it?"
- Step 5: Evaluation: Assess the effectiveness of the training (often using Kirkpatrick's model). Answers "Did it work?"

Which Adult Learning Theories Are Tested?
The PHR exam expects you to know that adults learn differently from children. Questions will test your judgment on selecting training methods that align with core adult learning principles. Memorizing these theories is the first step; applying them is what gets you the points.
| Theory | Core Principle | Exam Application |
|---|---|---|
| Andragogy | Adults are self-directed, bring experience, and are problem-centered. | Choose training that is relevant, practical, and allows for participant input. |
| Experiential Learning | Learning occurs through a cycle of experience, reflection, conceptualization, and experimentation. | Select methods like simulations, case studies, or on-the-job training. |
| Self-Efficacy | A person's belief in their ability to succeed in a specific situation. | Design training that includes early successes and positive reinforcement to build confidence. |
How Do You Conduct a Needs Assessment?
Before any training is designed, you must conduct a needs assessment to identify the performance gap. The PHR exam will test your ability to choose the right level of analysis for a given problem.
- Organizational Analysis: Examines the entire organization to determine where training is needed. It looks at strategic goals, available resources, and overall climate for training.
- Task Analysis: Compares the requirements of a specific job to the knowledge, skills, and abilities (KSAs) of employees performing it. This identifies the content needed for training.
- Person Analysis: Focuses on individual employees to determine who needs training and what specific skills they need to acquire.
What Career Development Strategies Are Tested?
Learning and Development isn't just about formal training courses. It also encompasses broader strategies for employee growth and organizational readiness.
- Coaching: A one-on-one process where a manager or expert helps an employee improve performance and develop skills.
- Mentoring: A longer-term relationship where a senior employee guides a junior employee's career growth.
- Job Rotation: Moving an employee through a series of different jobs to give them a broader range of experience.
- Succession Planning: Identifying and developing high-potential employees to fill future leadership roles.
