led. By a mere process of subtraction we may
determine the number of non-graduates, as well as the number of these
that fail, and then compute the percentage of the non-graduates who
fail. Thus we get 58.2 per cent (boys--62.5, girls--54.9) as the
percentage of the non-graduates failing. It is apparent at once that
this is almost identical with the percentage of failure for the ones
who graduate (Chapter II), but for the non-graduates the boys and girls
are a little further apart. It may be remarked in this connection that
no effort was made to include any of the 808 non-credited pupils among
the ones who fail. The inclusion of 60 per cent of this number as
potentially failing pupils, as was done in Chapter II, will raise the
above percentage of failing non-graduates by 11.5 per cent.

The above distribution of pupils enables us to determine what
percentage of the failing and of the non-failing groups graduate. These
percentages are identical--31.5 per cent in each case. The boys and
girls are further apart in the former group (boys--29.7, girls--33)
than in the latter group (boys--30.6, girls--32.1). It follows, then,
that the percentage who graduate of all the original entrants is 31.5
per cent. This fact varies by schools from 20.8 per cent to 45.4 per
cent. And such percentage is in each case exclusive of the pupils who
join the class by transfers from other schools or classes. Our
particular interest is not in how many pupils the school graduates in
any year, but rather in how many of the entering pupils in any one year
stay to graduate.

The greater persistence of the failing non-graduates, or the greater
failing for the more persistent non-graduates, has already been given
some attention in both Chapters II and III. In the following
distribution the non-graduates alone are considered. The number
persisting in school to each succeeding semester is first stated, and
then the percentage of that number which is composed of the non-failing
pupils is given.
