According to the Salesforce Education Cloud Consultant documents, the EDA Setting for Simple Address Change Treated as Update allows the system to update existing address records when a user makes a minor change to an address, such as correcting a typo or adding an apartment number. This prevents the creation of duplicate address records and ensures data quality. If this setting is disabled, the system will create a new address record whenever an address is changed, even if the change is minor. Reference:

Student Success Hub is a solution that enables schools to provide holistic support for students and families, especially in remote learning scenarios. It allows schools to create and track interventions, referrals, and services for students based on their needs and goals. It also provides dashboards and reports to monitor student progress and outcomes. Student Success Hub is built on top of the Education Data Architecture (EDA) and leverages the Program Management Module (PMM) and the Case Management Module (CMM) to deliver a comprehensive student support system.

The consultant should identify resource availability as a critical factor for the Advancement office's new Salesforce environment going live during a major capital fundraising campaign. Resource availability refers to the amount and type of resources that are needed and available for a project, such as staff, time, budget, or equipment. Resource availability is a critical factor for the Advancement office's new Salesforce environment going live during a major capital fundraising campaign, because it can affect the project scope, timeline, quality, and success. The consultant should assess and plan for resource availability to ensure that the project can be completed and delivered without compromising the fundraising campaign. Technical complexity, staff cross-training, and cost of the implementation are not critical factors for the Advancement office's new Salesforce environment going live during a major capital fundraising campaign.

The Household Account Model in EDA creates one account for each household and associates multiple contacts with that account. This model is suitable for tracking students' families and communicating with the parents on issues. The Household Account Model also provides features such as automatic household naming, address management, and rollup fields. The consultant should recommend this model for the primary school that will implement Student Success Hub.
