Statistics relating to the medical gradings of men called 
      up under the National Service Acts for examination by Medical 
      Boards before entry into the Services (Navy, Army, Air Force 
      or Civil Defence) are given below. They include men called up 
      under the Military Training Act during the three months before 
      the war began. They do not include men entering the Regular Forces 
      before the war, Reservists or Territorials called out on the 
      outbreak of war, nor men joining any of the Services voluntarily 
      during the war..
 
      
 
 
Medical Boards classify men in four Grades defined as follows: 
      -
 
      Grade I - men who, subject only to such minor disabilities as 
      can be remedied or adequately compensated by artificial means, 
      attain the full normal standard of health and strength and are 
      capable of enduring physical exertion suitable to their age.
 
      
 
 
Grade II - Those who, while suffering from disabilities disqualifying 
      them for Grade I, do not suffer from progressive organic disease, 
      have fair hearing and vision, are of moderate muscular development, 
      and are able to undergo a considerable amount of physical exertion 
      not involving severe strain
 
      Where a man has been placed in this Grade solely on account of' 
      either defects of visual acuity or deformities of the power extremities, 
      or both, the letter '(a)' followed by the words "vision" 
      or "feet" in brackets, will be inserted after the grade, 
      i.e. "Grade II (a) (vision)" or "Grade II (a) 
      (feet)".
