Way forward After the Training

Participants will develop a work plan through the help of facilitators that stipulates application of skills acquired in improving their organizations. ASPM will continuously monitor implementation progress after the training.

Training Evaluation:

Participants will undertake a simple assessment before the training to gauge knowledge and skills and another assessment after the training in-order to monitor knowledge gained through the training
