By 1925 the membership of the association had grown to 2000, but the effects of the Second World War reduced the membership to 1,189 by 1939 and 753 in 1946. To diversify its services, the association started operating a driving school in 1962 beginning with a single Ford Anglia.
The idea was introduced by the late M.A.S Northcorte and other former British army men. Respected for its strictness, in depth curriculum and commitment to responsible driving AA has become one of the most favoured driving schools on the continent.
In the year 2000 AA Kenya completed the construction of it's million dollar headquarters comprising a highly equipped garage. At present the association has over 100,000 members and branch offices in all major towns countrywide.
Internationally, AA Kenya is affiliated with Fédération Internationale de l'Automobile (FIA) which represents over 100 million motorists worldwide.
