Scoliosis Research Society (SRS) offers five levels of grants:

Small Exploratory Grant
This grant is designed specifically for new investigators who have a preliminary concept they would like to develop into a research project. The maximum grant award for this category is $10,000. The maximum duration of research is one year. The grant application should be no longer than five pages, and does not require pilot data. It should, however, be able to generate pilot data that could be used when applying for a larger grant.

New Investigator Grant
This grant is specifically targeted to new investigators. This grant will not be awarded to those who have received prior funding from national granting organizations, such as SRS (standard grant), OREF, NSF or NIH; though it is available to candidates who have received a Small Exploratory grant. The maximum award is $25,000; and, the duration of research may extend up to two years. Preliminary data is suggested although not absolutely required, and the application should be limited to seven pages.

Standard Investigator Grant
This grant is awarded a maximum of $25,000 per year up to two years’ duration, the maximum total award being $50,000. These grant applications may be in any area of spinal deformity research, although an additional funding source for grants focusing on the etiology of scoliosis is available in conjunction with the Cotrel Foundation. These grant applications require evidence that the investigator has the experience and resources to complete the proposed research. As such, preliminary data is generally required. The application is limited to 15 pages.

Alf Nachemson Evidence Based Medicine Grant
The award is given to studies that aim to provide the best available evidence by which to improve our knowledge and practice in the care of patients with spinal deformities. These grant applications require evidence that the investigator has the experience and resources to complete the proposed research. This grant awards a maximum of $25,000 per year up to two years’ duration, the maximum total award being $50,000.
