How a Survey is Completed

(TREC #7724)

1      Introduction

1.1    Purpose of Course

This course will introduce the learners to how surveys are competed, both historically and in the modern era. This course provides 2 hours of continuing education for Realtors.

1.2    Course Description

Discrepancies are inevitable when comparing any surveys. These discrepancies compound when dealing with aged surveys. This course teaches Realtors to recognize the limitations of older surveys and thereby assist their clients to manage their expectations when relying upon them.

1.3    Target Audience

Tennessee Realtors who may be expected to explain to a client why a boundary survey differs from one surveyor to another.

1.4    Knowledge and Skill Prerequisites

The following knowledge and skill prerequisites are required from the participants:

  • English language skills
  • Basic math skills

1.5    Delivery Methods

This course is divided into 2 – 1-hour modules. Each module is comprised of individual lessons conveying information required for subsequent lessons.

Delivery of information takes place in a classroom setting as an interactive lecture. Graphic augmentation of the lecture content uses Prezi, PowerPoint, or slides/handouts. (Instructor will modify depending on available technology in the room.

 

2      Course Overview

2.1    Course Goals

Given access to the appropriate information, the participant should be able to:

  • Determine the era of origin of a legal description.
  • Identify potential issues that can arise from old surveys.
  • Describe the methods utilized in surveying.
  • Explain the reasons why surveys are not identical.

2.2    Learning Environment

The course will be offered in any venue that “contains adequate space, seating, and equipment” (TREC Rule 1260-05-.03(1)(b)) and not prohibited by TREC Rule 1260-05-.06(1)(a) “conducted in a facility which is also utilized for conducting business of a broker or brokerage firm.”

The layout and availability of equipment will dictate the use of overhead projection or paper handouts.
