What to look for in an executive coaching method
- It goes below behavior. The method works on the thoughts, beliefs and emotions behind how a leader acts, not only on goals and action plans.
- It addresses stress. Leaders often act differently under pressure, so the method should show that pattern and help change it.
- It measures change. An assessment at the start and again later shows whether anything moved.
- It is taught to a standard. Look for ICF-accredited training and credentialed trainers.
How Core Energy Coaching™ works with executives
Core Energy Coaching™ is iPEC®’s method for getting to the root of a leader’s challenges. Coach and leader identify the inner thoughts, beliefs and emotions that block success, then shift them to create sustainable change.
The method describes two kinds of energy. Anabolic energy is constructive and growth-oriented. Catabolic energy is draining and often comes from self-protection. It can help in a short-term crisis, but it costs a leader over time.
A typical coaching engagement:
- Baseline. The leader takes the Energy Leadership Index® (ELI) assessment, which shows how they tend to operate day to day and under stress.
- Debrief. The coach and leader review the results and connect them to real situations at work.
- Coaching. Sessions uncover blind spots and limiting beliefs, then build new ways of responding.
- Re-measure. The leader retakes the ELI to see what changed. In one iPEC® study, clients who retook it every 6 to 8 months saw strong gains.
What the research shows
Coaching in general. A 2023 meta-analysis in Academy of Management Learning & Education combined 37 randomized controlled trials of workplace and executive coaching, covering 2,528 participants. It found a significant effect on leadership and personal outcomes. Reviews like this test coaching overall. They don’t rank named methods.
Core Energy Coaching™ and leadership. An iPEC® study looked at 184 C-suite executives and managers and 4,008 colleagues who rated them. On average, leaders with higher ELI scores rated themselves higher on every leadership competency. Colleagues also rated them higher on every competency, most clearly on engagement, communication, relationships and problem-solving.
Change over time. A 2022 iPEC® study followed 2,545 coaching clients who took the ELI before and after coaching. Clients coached for 6 to 12 months moved from an average energy level of 3.22 to 3.46 on the 7-level scale. Overall life satisfaction rose from 4.23 to 4.53 on a 6-point scale.
The limits. Both studies come from iPEC®, and they rely on assessment ratings. Neither compared coached leaders with leaders who weren’t coached, so they show a relationship and not proof of cause. Read the research papers.

Frequently asked questions
What is Core Energy Coaching™?
Core Energy Coaching™ is iPEC®’s coaching method. It gets to the root of a person’s challenges by identifying the inner thoughts, beliefs and emotions that block success, then shifting them to create sustainable change.
How is Core Energy Coaching™ different from traditional executive coaching?
Traditional coaching often centers on goals, action steps and accountability. Core Energy Coaching™ uses those goals as a starting point and works first on the beliefs and emotions driving a leader’s behavior.
How do you measure the results of executive coaching?
With Core Energy Coaching™, the leader takes the Energy Leadership Index® (ELI) at the start of coaching and again later. Comparing the results shows how the leader’s energy changed, including under stress.
Is there research on Core Energy Coaching™?
Yes. iPEC® has sponsored studies of leaders and coaching clients using the ELI, and the papers are on iPEC®’s research page. They show positive relationships but don’t compare coached leaders with leaders who weren’t coached.
How do coaches get certified to use the ELI?
The Energy Leadership Index Master Practitioner (ELI-MP) certification is earned only through iPEC®’s Coach Training Program.
