We have presented here the numbers that graduate without failures, together with the total group to which they belong, and the same for the graduates who have failed. 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.
