Agarose gel electrophoresis is a comparatively easy technique and requires limited knowledge & expertise, reagents, instruments and space.
KNOWLEDGE AND EXPERTISE
Pipetting: Handling micropipette is the major skill you need to load an accurate amount of your samples onto the wells of agarose gel without damaging the gel.
Handling of samples: You must have knowledge of working with nucleic acids, especially RNA as it is prone to degrades.
Safety procedure: Some of the chemicals like nucleic acid staining dyes, formamide (for denaturing agarose gel electrophoresis) etc must be handled carefully. You must be aware of the hazardous effects of these chemicals on human health and environment, and must use appropriate procedures to handle and discard these chemicals. You must also know the hazardous effects of uv light on humans as you need this to visualize nucleic acids embedded in agarose gel.
