NIRISS Example Science Programs
NIRISS example programs are available to walk users through all elements of a JWST observing program, from posing a question to identifying an instrument-specific mode optimized to answer that question. These examples use Exposure Time Calculator (ETC) simulations to estimate reasonable exposure times, and illustrate how to specify the observations in the Astronomers Proposal Tool (APT).
Here is a list of all NIRISS-related example programs:

JWST proposals require significantly more preparation compared to HST proposals. As part of the single stream process, JWST proposals will require a detailed technical justification and, in most cases, a complete Astronomers Proposal Tool (APT) program.
While APT provides templates for some of the most common observing modes, some observing scenarios are more complicated. The science use cases listed above provide a guide to crafting the technical aspects to your proposal, including how to use the Exposure Time Calculator (ETC) and APT.
Accessing ETC workbooks and APT files for the example science programs
Each example science program has an attendant ETC workbook and APT file that can be used for reference as you work through each example. The relevant ETC workbooks are available within the ETC itself. A tab in the ETC GUI allows access to a drop-down menu that shows the example science program workbooks with the same titles and reference numbers shown in Table 1. Select the example workbook of interest and add it to your personal list of ETC workbooks to access the contents as shown in Figure 1.
