{url} The Caltrans exam is online for landscape maintenance worker . It is based on experience , whether voluntary or not . He would want to do the best job he can the first time , because he can only take the test once per year . That 's just an example of the 40000 + jobs the state offers . Give me a call if you ever have any questions . You may have to help him through the entire process , but I guarantee you it 's worth it ! Mae
