Overview of County Appraisal District1.1
County History and DemographicsRockwall County was formed in 1873 from part of Kaufman County and named for a rock formation that runs through the county.
Rockwall County is located on the Blackland Prairies of north central Texas approximately 25 miles northeast of Dallas. Rockwall County is surrounded by Kaufman County on the south, Hunt County on the East, Dallas County on the west and Denton County on the North.
Ninety three percent of the county is arable and extremely fertile. The greater part of Rockwall County is a treeless prairie although there was once heavy timber along the East Fork of the Trinity River.
The population of the county for 2003, according to the County Information Project, was 54,630 residents, with the City of Fate having 1,252 residents, the City of Heath having 5,878 residents and the City of Rockwall having 24,624 residents. The balance of the county population 22,876 residents lives in other cities and towns and the rural areas. The county comprises 149 square miles and is the smallest county in Texas.
The county seat is Rockwall, located at the intersection of Interstate Highway 30 and State Highway 66. The city became the county seat when the county was formed in 1873.
The county includes the Rockwall Independent School District, and Royce City Independent School District.

Appraisal District Organization and StaffingThe appraisal district was formed in 1981 and became active in 1982. Rockwall CAD has a total of 12 full time staff with two supervisory positions and one part time position. Five of the positions are full time appraisers. The district contracts with Capitol Appraisal Group for professional appraisal services of utility appraisals. Also, the district provides collection services for seven of the eight taxing units they appraise; Rockwell County does their own collection. The CAD has a total of 4 full time staff with one supervisory position and one part time position for collections.
Exhibit 1 outlines the district organization.
Scope of Office
The Board of Directors has no authority to set values or appraisal methods. The chief appraiser carries out the appraisal district's legal duties, hires the staff, makes the appraisals and operates the appraisal office.
The appraisal district is responsible for appraising 53,600 parcels of real, mineral and personal properties located within the boundaries of the district. This includes 6,229 parcels of business personal property. The appraisal district contracts with Capitol Appraisal Group (CAG) for professional appraisal services; CAG appraises utility property.
The district provides appraisal services for eight taxing units, Rockwall County, Rockwall Independent School District, Royce City Independent School District, City of Fate, City of Rockwall, City of Royce City, City of Heath, and Rockwall County MUD #1.
Exhibit 2 presents the types of properties appraised by Rockwall CAD in tax year 2003. In-house staff handles most property categories except Category J (utilities), which is appraised by CAG.

Most appraisal districts contract out some of its appraisal to contract appraisal firms. PTD does not track parcel counts appraised by external appraisers in appraisal districts. Appraisal district contracts with external appraisers routinely do not include a parcel count for the number of appraisals an external appraisal company will perform. In assessing the staff to parcel count ratio in each appraisal district, PTD uses parcel counts reported in the district's 2003 and the county's independent school districts self reports to calculate the parcels per appraisal district staff. PTD does include all of the commercial real and personal property parcels in the calculation, since PTD is unable to determine exactly how many parcels are assigned to in-house staff versus a contract appraisal firm. The total parcels appraised in-house are calculated by summing the total number of parcels reported in Categories: A, single family residential; B, multifamily residential; C, vacant lots; D, rural land; E, rural improvements; F1, commercial real property; L1, commercial personal property; M1, mobile homes; O, residential inventory; and S, special inventory, as shown in Exhibit 3 below.

The International Association of Assessing Officer (IAAO) Standards state that small taxing units run from 1,500 to 1,700 parcels per staff member and large taxing units run from 3,000 to 3,500 parcels per staff member with an average of 2,500.
Districts comparable in size to Rockwall are Gillespie, Palo Pinto, Val Verde and Atascosa. The number of parcels per staff member for Rockwall CAD was 2,640. Gillespie CAD was 3,280, Palo Pinto CAD was 2,297, Val Verde CAD was 2,469 and Atascosa was 2,383. Of course, workloads in appraisal districts may vary, sometimes drastically, due to any number of considerations other than parcel count. Geography or the size of an appraisal district may have a significant impact on the time required to work all parcels. The types of properties may also have an impact. More complex commercial and sometime even residential properties may require more staff to appraise. The data given here is meant to give the reader at least some comparison to other appraisal districts with similar parcel counts and the standards determined by IAAO. A valid comparison of collection services could not be made as none of the districts used in comparison do collection services except Rockwall CAD.

Self Evaluation QuestionnaireIn preparation for the Appraisal Standards Review, Rockwall CAD was requested to complete the IAAO's Self Evaluation Questionnaire. This instrument allows an appraisal district to assess their compliance with acceptable procedures, standards and organization. Each district receives an electronic version of the question and the complete IAAO manual explaining each questionnaire with information on how to answer each question. Each district undergoing an appraisal standards review is requested to perform the self assessment, with the goal of assisting the district in determining how well it is performing.
Rockwall County answered 109 out of 110 questions, mostly in the affirmative when appropriate and negative when appropriate. The district did elaborate in the areas where they felt an explanation was needed instead of responding with a yes or no answer. This made the overall assessment based on the district's responses much easier.
The answer to the questions helped the reviewer to evaluate the districts operations and supported the findings reported.
The IAAO self-assessment questionnaire was provided with the IAAO self assessment guide. In the guide's introduction, it stated
The guide is designed for use by individuals who want to evaluate their own procedures and who are seeking to either continually improve or to evaluate their procedures against what is believed to be a standard of best practices in assessment administration.
The Comptroller provided the questionnaire and the guide to the district to allow it to perform a self assessment of its operations and help it recognize areas where it is doing a good job and areas where it needs to improve.

Findings of the Property Value Study and Summary WorksheetsThe Property Value Study (PVS) determines the total property value in each school district in the Rockwall County Appraisal District (CAD). With a few notable exceptions, all CADs and the Property Tax Division (PTD) are required by law to appraise property at market value. Agricultural land and timberland are appraised according to productivity value. Market value, in short, is the price that a property would transfer from a willing seller to a willing buyer. For it to be a market transaction, neither party may be under duress to buy or sell, the sale must be on the market for a reasonable time and the parties to the sale are not related.
Local tax roll value, or local value, is determined by the county appraisal district and submitted to PTD on its annual self-report. The PTD staff estimates the total taxable value in a school district, referred to as state value, by determining market value or by accepting the local appraised value in each property category (see Exhibit 2) in the district and then adding these category values for an overall school district value. PTD then deducts state-mandated homestead exemptions, disabled veterans' exemptions, value limitations, reinvestment zones, freeport exemptions, the loss between market value and productivity value appraisal of qualified agricultural lands, the school tax ceiling for homeowners over age 65 or disabled and other state-mandated exemptions.
PTD issues a preliminary and final PVS each year. School districts and county appraisal districts may protest the findings of the preliminary PVS through an administrative hearings process with the Comptroller, and school districts may protest the findings of the final PVS in district court. The administrative hearings process requires the protester to file a written protest with supporting documentation within 40 days of the issuance of the preliminary PVS. The PTD may amend the findings of the preliminary PVS based on the submission of the written protest, an informal hearing or a formal hearing. Formal hearings are held by a hearings examiner, appointed by the Comptroller's General Counsel, and reporting directly to the Comptroller. The hearings examiner is not an employee of the PTD.
When conducting the property value study, PTD assigns properties to various categories, such as residential, commercial and rural property. Properties are divided into categories so that like properties are assessed together.
Rockwall CAD did not appeal the findings of the preliminary study. Rockwall ISD and Royce City ISD did appeal the findings of the preliminary study. Despite the changes, the Royce City school district was unable to get into the confidence interval and was certified an eligible district in June 2004.
A review of the school districts in the county indicates that Rockwall CAD is inconsistently appraising the single-family residence properties and consistently appraising rural residences below market value as determined by the PTD. In the 2003 PVS, Royce City school district fell outside the study's statistical margin of error. Rural residences (subcategory D2) are the primary reason that the school's values are not within the acceptable range determined by the study, while single-family residences (Category A) played a borderline roll.
There are four property categories tested in Royce City Independent School District (ISD): (1) category A, Single-Family Residences, making up 51.2 percent of the district's value with a weighted mean ratio of .9566; (2) category C, Vacant Lots, making up 7.9 percent of the district's value with a weighted mean ratio of .9565; (3) category D, Rural Real, making up 17.6 percent of the district's value with a weighted mean ratio of .8637; and (4) category F1, Commercial Real, making up 5.1 percent of the district's value with a weighted mean ratio of 1.0140. In general, a ratio of between .95 and 1.05 in any property category makes it more likely that the district is appraising property within the margin of error, or that it is appraising property at or near market value, according to the PVS.
Royce City ISD is outside the confidence interval limit. Royce City ISD's category A makes up 62 percent of the tested value. The appraisal district is placing a value on the category A single-family residences below their market value with a weighted mean ratio of .9566. The low weighted mean ratio in category A is one of the categories causing the school district to be identified as eligible. Although category C, vacant lots, are also appraised below market value with a weighted mean ratio of .9565, it is not the primary reason that the school's values not within an acceptable range as determined by the study. Category D, Rural Real, is also appraised below market value with a weighted mean ratio of .8637. Category D represents rural properties and contains two subcategories: D1 and D2. Subcategory D1, Productivity Value of Qualifying Acres, is primarily farm and ranch land that qualifies for the special productivity appraisal. Subcategory D2, Non-Qualifying Acres and Farm and Ranch Improvements, is primarily rural homes and land that does not qualify for farming or ranching or timberlands. The differences in value between qualified and non-qualified rural land are often wide since D1 land is appraised using a special statutory method to determine the lands productivity value and D2 is based on what the land would sell for in an open market transaction. Royce City ISD's subcategory D1 makes up only 4.9 percent of category D's value and 1.1 percent of the tested value. D1 Productivity Value properties tested at a weighted mean ratio of 1.1164. Category D2 makes up 95.1 percent of category D's value and 21.3 percent of the school district's total tested value. Overall, category D2 is being under appraised with a weighted mean ratio of .8538. The low weighted mean ratio in category D2 drops the district outside the margin of error causing the school district to be identified as eligible. Category F1, Commercial Real, is appraised at market value with a weighted mean ratio of 1.0140. Category F1 is not the primary reason that the school's values are not within an acceptable range as determined by the study. The low weighted mean ratio in categories A and D2 drops the district outside the margin of error causing the school district to be identified as eligible.
In additional to Royce City ISD, the other school district in the county is Rockwall ISD.
Rockwall ISD is within the confidence interval limit. Category A is 70 percent of the school district's value and makes up 82 percent of the tested value. The appraisal district is placing a value on the category A single-family residences at market value with a weighted mean ratio of 1.0111. Category D is 4.9 percent of the school district's value. Category D, Rural Real, is appraised below market value with a weighted mean ratio of .9692. Rockwall ISD's subcategory D1 makes up only 1.7 percent of category D's value and 0.1 percent of the tested value. The appraisal district is placing a value on the D1 Productivity Value properties above market value by a weighted mean ratio of 1.2592. Category D2 makes up 98.3 percent of category D's value and 6 percent of the school district's total tested value. Overall, category D2 is being under appraised with a weighted mean ratio of .9652.
In summary, the Rockwall CAD should focus its energies on its valuation of subcategory D2, Non-Qualifying Acres and Farm and Ranch Improvements, and to a lesser extent category A, Single-Family Residences. In category D2, Non-Qualifying Acres and Farm and Ranch Improvements, both school districts in the county tested well below market value. Category A, single-family residences tested well below market value in Royce City ISD in the value ranges of $35,000 to $110,000.
For a statistical explanation of why the district was selected as eligible, see Appendix 18.
