For many installations the resistance of the earth electrode can be measured using an earth fault loop impedance test instrument.
This test is explained in the video. Further information is contained in Chris Kitcher's 'Practical Guide to Inspection, Testing and Certification of Electrical Installations', p74-90, see link above.
