The activities of the chapters are carefully supervised by the national officers, and finances are subject to supervision of a finance committee with a majority of members selected from alumni and faculty, to insure stability and good judgment. Charges to members are as low as possible, and usually below those of most other fraternities. There are no required alumni dues. Scholarship of the chapters is invariably high compared with most other fraternities. The fraternity publishes a magazine, The Castle , to which the member is entitled for life, without any charge after he leaves school.
Chapters maintain a social program planned to meet the needs of the members.
The professional program, which is required, is usually broad in scope. It includes forum discussions, symposiums, and addresses. The members often put on the programs, but guest speakers, often of considerable prominence, frequently participate. The subjects considered are by no means restricted to engineering, and thus frequently provide the broader contacts, which the professional social fraternity sometimes falls to offer. Sigma Phi Delta offers no apology for its existence.
