For over thirty-five years, ESF has been offering its clients' a variety of material, tools, and processes to enable an organization's employees to become Professional Trainers in each aspect of the trainer's job.

ESF can help you with the following training areas:

Over the past thirty-five years, ESF has developed many fantastic courses for a variety of clients including:

  • Prime Time Sister Circles® (PTSC): Drs. Marilyn Gaston and Gayle Porter have shaken the over 55 African American women's population by creating a potentially-effective intervention for women to make lifestyle changes with Prime Time sisters and within Prime Time Sister Circles® using the Prime Time Curriculum and Workshops developed by ESF.

ESF does not bid on projects, submit lengthy proposals, or write progress reports for work done. We are a small company and prefer to spend our time working with our clients, not competing against other development companies, or writing up our day-to-day accomplishments. We start work on a verbal go-ahead or a handshake. Our prices are fair. We work fast. We meet our deadlines. Most of our contracts come from word-of-mouth referrals: our clients tell others about the professional results they achieved through the programs we developed for them.

Sustained Impact of ESF's Work...

Advancing the Field of Workplace Learning & Performance

Over the course of almost forty (40) years, Drs. Peter and Mary Esseff conducted applied Research and Development in the field of Instructional Technology by applying their theories and philosophy to the projects they worked on for their clients. In so doing, they redefined the application of Instructional Technology and created the most effective instructional systems design model available to date. ESF's IDLS Instructional Design Model is a five-step process including the following:

Step 1: Create a Task Analysis:

ESF developed a Task Analysis process to determine what learners need to DO (and LEARN to do) to PERFORM their job tasks successfully.

ESF's IDLS Instructional Design Model for creating a Task Analysis is three-fold:

  1. Review Existing Documentation,
  2. Get Subject Matter Expert (SME) Review, and
  3. Conduct On-site Observation.

Doing R & D over several years, the Esseffs developed TaskOutliner, a unique software system that instructional systems designers use to create Task Analyses quickly, easily and effectively.

Step 2: Write Performance Measures:

ESF developed a process to create Performance Measures from the finalized Task Analyses developed above. The Esseff IDLS Performance Measures Model includes written Pre, Progress, and Post Inventory Questions (Multiple Choice and Matching) and "hands-on" Performance Measures (Case Studies, Role Plays and Demonstrations) along with Performance Checklists.

Step 3: Develop Learning Materials:

ESF developed a process of designing and developing Learning Materials (both in written and computer-based format) that are entirely interactive and are developed from the two previous steps described above. The materials in the Esseff IDLS Learning Materials Development Model are self-paced and include Pre, Progress and Post Inventory Questions, Narrative Content, and Graphics. Learners' Guides include Activities and instructions for applying what learners learned in the self-paced materials. Over the course of several years R & D, the Esseffs developed StyleDoc, a software system that allows instructional systems designers to customize instructional materials easily, quickly and consistently. The Esseff IDLS Model allows for immediate transfer of learning materials to a computer-based format, either CD or Web-based.

Step 4: Validate Materials:

ESF developed a Validation process that GUARANTEES learning. The Esseff IDLS Validation Model provides a field test of the Learning Materials described above. The Esseff Validation process is unique in the learning industry in that it ensures that all learners achieve 90% or better on the objective Post Inventory Questions and 100% on the Performance Checklists which contain only observable tasks and subtasks.

Step 5: Create Interactive Instructor's Guides and Presentations:

ESF developed a process to create Instructor's Guides and Interactive Instructor Presentations quickly and easily. The Instructor Guides and Interactive Instructor Presentations ensure consistency in presentation in style and format from instructor to instructor.

Thanks ESF...

I have been using the IDLS methodology for the past 10 years. When implemented correctly, I have always met with success. The knowledge and experience incorporated into your programs make them easy to understand and apply. The methods make common sense! Thank you for your continued support.
