Captain Corwin was of the opinion that the former method was the most satisfactory, although the Morris High School, which won the Whitney trophy in 1906, adopted the latter method.
The league established a marksmanship badge, to be awarded, as in the National Guard and in the Army, to each boy who annually showed satisfactory proficiency in shooting. The qualifying score first adopted for this badge was 40 out of a possible 50 "off-hand." It was found almost immediately that the boys were shooting so well that it was necessary to raise the standard, which was therefore increased to 42 and later to 43.
The following is a list of the number of boys who qualified as marksmen in their respective schools during the year 1906:
| Boys' High School | 45 |
| Bryant High School | 18 |
| Commercial High School | 6 |
| Curtis High School | 24 |
| De Witt Clinton High School | 23 |
| Morris High School | 16 |
| Erasmus Hall High School | 15 |
| Manual Training High School | 23 |
| High School of Commerce | 19 |
| Stuyvesant High School | 8 |
| Total | 197 |
The qualifying score has now been raised to 44.
The Brooklyn Eagle assumed the expense of manufacturing and presenting these badges, which consisted of a Maltese cross having crossed rifles, the seal of the league, which is the "Winged Victory," in the center, the whole being suspended from a bar with the word "Marksman" on it, and the date.
During the spring of 1906 a large number of interscholastic competitions were held. These were found valuable, not only in broadening the boys' ideas in respect to shooting, but in helping their nerve in competitions.
On June 1 and 2 the annual interscholastic competition for the Whitney trophy was held. Instead of having each team shoot in its own school it was decided to have them shoot together at the Seventy-first Regiment Armory as neutral ground, under the supervision of Captain Corwin as range officer. The following were the scores, the conditions being the same as above stated:
| Morris High School. Instructor E. M. Williams | 359 |
| Curtis High School. Instructor O. M. Curtis | 356 |
| High School of Commerce. Instructor Charles Jamison | 355 |
| De Witt Clinton. Instructor Emanuel Haug | 354 |
| Manual Training High School. Instructor Ernest G. Muller | 350 |
| Bryant High School. Instructor George W. Norton | 349 |
| Erasmus Hall High School. Instructor J. M. Tilden | 348 |
| Stuyvesant High School. Instructor M. F. Goodrich | 348 |
| Boys' High School. Instructor W. H. Andrews | 340 |
The two best scores were not as high as were made in 1905, largely owing to the strain of shooting in actual competition and among strange surroundings. But the average was better and the scores were closer.
