Training Types

INSTRUCTOR-LED TRAINING

Instructor-led training is an effective means of delivering information, as it allows for real-time feedback, questions and answers, manipulation and changeable delivery to suit the needs of learners in a real-time environment. Few educational opportunities are considered more valuable than meeting and interfacing directly with an instructor. 

 

All of our trainers are MCPs [Microsoft Certified Professionals], ECDL certified and MOS Experts which guarantees that the training you receive will be of the highest quality.

 

PFH has a large portfolio of trainers who can deliver training at our training centres in Cork and Galway, or Nationwide at customer premises or another training centre.

 

PFH offers instructor led training on our Public Schedule at our training centres in Cork and Galway. 

 

CUSTOMISED INSTRUCTOR- LED TRAINING

PFH provides customised training for groups of 1 to 12 at either PFH's Training Centres at Cork or Galway or on-site at your premises. Content can be taken from any of our course oulines and customised to suit the exact requirmements of your group and scheduled on dates that suit your delegates.  Group rates apply contact us for rates.

 

This method of training ensures your delegates get trained on exactly the topics they require in the duration of time that you can allow to give them.

 

SEMINAR STYLE TRAINING

Seminar training can be offered where companies require a large number of people to receive initial overview training on the New Interface of an Operating System or Office Applications. 

 

Seminar Training is based solely on demonstrating the New Features and is non hands-on training.  The benefits of this type of training is that attendees can get an initial feel for the New Interface of any given application and it can save a lot of time and money during an initial roll out.  This type of training instils an element of confidence when people return to their desks to work with the New Interface or Application.

 

Depending on how the roll out is managed with the installations, training could be run in tandem with this, and groups may also benefit from the trainer doing some “floor walking”  following the seminars to assist people when they are back at their desks.

 

The number of attendees is optional and can range from 20-50 per session.  This is dependant on the size of your room!

All training/seminar can be customised specifically to suit group requirements.
