Respondent. )
A hearing was held in this case on March 23, 1988 in Sarasota, Florida before Arnold H. Pollock, Hearing Officer. The issue for consideration is whether Petitioner's answers to the Professional Engineer Examination were properly graded.
For Petitioner: Kristina V. Tignor
For Respondent: H. Reynolds Sampson, Esquire
On July 22, 1987, the Petitioner, Kristina V. Tignor, was notified by the State of Florida, Department of Professional Regulation, Office of Examination Services, that she had failed the Professional Engineer examination given on April 9 and 10, 1987. She requested reconsideration of the grade given certain answers she provided and thereafter requested a formal hearing. The matter was referred to the Division of Administrative Hearings and initially set for hearing on December 15, 1987. However, the parties requested several continuances and the case was ultimately heard on March 23, 1988.
At the hearing, Petitioner testified in her own behalf and presented the testimony of William F. Bishop, a registered civil engineer and the Petitioner's employer. She also introduced Petitioner's Exhibits 1 through 4. Respondent introduced the testimony of Dr. Bruce A. Suprenant a registered professional civil engineer, and, by deposition, the testimony of Kenneth E. Weldon, the Assistant State Drainage Engineer for the Florida Department of Transportation. Respondent also introduced Respondent's Exhibits A through D. No transcript of the proceedings was provided. Respondent submitted Proposed Finding of Fact which have been ruled upon in the Appendix to this Recommended Order.
Petitioner herein, Kristina V. Tignor, took the Professional Engineers Examination for the State of Florida in Orlando on April 9 and 10, 1987. On July 22, 1987 she was advised by the Department of Professional Regulation's Office of Examination Services that she had failed the examination and was given a cummulative score of principles and practice of 69.1 percent.
In her initial request for review and reconsideration, Petitioner objected to the points assigned to her solutions for three problems on the test, Numbers 425, 421, and 124. She contended that as a working engineer, certain criteria and assumptions must be made in approaching any engineering problem and, because the portion of the examination in issue is graded subjectively, her answered should be reconsidered and evaluated in that light.
At the hearing, Petitioner contested only the grading of questions number 124 and 421, thereby accepting the grade given for question 425.
With regard to Question 124, Ms. Tignor was awarded a score of 5 on her solution to this problem. The National Council of Engineering Examiners, in its Standard Scoring Plan Outline awards a "qualified" evaluation to scores from 10 down to 6 on this question. Scores from 5 to 0 are rated, "unqualified." A score of 5 indicates the applicant has failed to demonstrate adequate knowledge in one aspect of one category. Specifically, a rating of 5 in this question indicates that the examinee displayed an inadequate knowledge of weight/volume and concrete mix design. Her computations were displayed and an incomplete or erroneous solution was arrived at which gave a generally unrealistic result.
Dr. Bruce A. Suprenant a civil engineer registered in four states and who teaches engineering at the University of South Florida, reviewed the question, the Petitioner's solution, the solution proposed by the examiners, and the grading scheme for this problem and found a number of illogical items in Petitioner's solution which, to him, were difficult to understand. He found several items which had no basis and which were possibly assumed.
As to Part a of Petitioner's answer, a mixture of answers, (correction for moisture), which should have been in Part b, was located in Part a. As to density, the value used by Petitioner does not appear to be reasonable based on information provided in the problem.
In Dr. Suprenant's opinion, there are at least three approaches to this problem. One is the water/cement ration method. Another is the weight method. The third is the absolute volume method. The water/cement ratio method would be difficult to apply here and neither Petitioner nor the examiners used it. As to the weight method, much the same problem exists. There is insufficient information provided to satisfactorily apply this method and while the examiners did not use it, Petitioner did.
Petitioner's answer has a correction for moisture in the absolute volume method on the first page of the solution form at the top. The calculations by Petitioner are assumed information not known, (volume). In addition the correction for moisture in the second part of page one is included on the top of page two. It is not a part of the solution for subpart a and should not be there.
Petitioner used 150 pounds per cubic foot for concrete density in her solution and this choice is not explained. Most publications utilized by engineers suggest using tables which were not provided to the examinees and it is, therefore, illogical to assume concrete density with no history for that assumption. Petitioner's answer of 5.41 cubic yards is only slightly off the suggested answer of 5.44 cubic yards but the fact that the answers are close does not justify her assumption. It might well not come so close in other cases.
As to Part b of the question calling for the water/cement ratio, the corrections for moisture of fine and coarse aggregate on page one are acceptable. On the second page, a problem arises in when the correction for moisture should decrease. Petitioner got the right factor but applied it in the wrong manner. As a result, her answer to Part b of the examination question is wrong. Her answer was 4.40 as opposed to the correct answer of 4.34. This small degree of error can be attributed to the smallness of the amount in question. Were the amounts greater, the error would be greater.
As to part c of the question, which deals with the cement factor in a yard of concrete, Petitioner's approach of dividing sacks of cubic yards is correct, but the cubic yard content was determined from Part a of the question, and Dr. Suprenant does not agree with how she got her solution. He therefore questions her carryover. The standard weight of a sack of concrete is 94 pounds.
The individual grading Petitioner's response to Question 124 indicates she displayed inadequate knowledge and reached a solution which gives "unrealistic results." Dr. Suprenant agrees, contending that Petitioner's performance in regard to this question indicates inadequate knowledge of weight/volume relationship. She made inadequate assumptions in formulating her answer to the question. The fact that in this problem she arrived at a solution close to the correct one does not indicate that in other problems, she would achieve the same closeness using the same procedure. In his opinion, Petitioner showed some confusion regarding the basis for solving this problem and Dr. Suprenant believes that a grade of 5 as awarded by the examiner is correct.
Petitioner questioned the fact that the various technical weights and volumes, such as 94 pounds in a sack of concrete, 8.33 pounds for a gallon of water, and 27 cubic feet in a cubic yard do not appear in the problem statement. This, in the opinion of Dr. Suprenant, compounds the gravity of Petitioner's deficiency. They are routine "givens" generally accepted in the practice by engineers and it would be difficult to assume that anyone familiar with the practice of engineering would use different "givens" for these specifics.
Petitioner's employer, Mr. Bishop, himself a registered civil engineer in Florida since 1958, also reviewed Petitioner's solution to Question 124. He admits that on the first page of the answer sheet, Petitioner began solving the problem in an inappropriate way. Her calculations for moisture content were correct, however. On the second paged the correction factor was put in with the wrong sign and the aggregate was given the wrong factor. As a result, the answer was off. In his practice, however, the error committed by Petitioner in these regards is both minimal and acceptable.
Her choice of 150 pounds per square foot is reasonable and produced a close result, and while it is true that if the project were of a greater scale, the error might be significant for a test question, as here, the error, in his
opinion, is insignificant. He feels much the same way regarding the error in Part c of the examination question.
While the factors used by petitioner were wrong, the process used was correct and the answer was not unreasonably incorrect for a test solution. In an examination situation, the calculations are not being done on a continuous basis, and he feels the grade of 5 awarded is unduly harsh since the error was numerical rather than operational. In his opinion, a more reasonable grade would have been a 6 or 7.
Petitioner began her solution to this problem by using one similar to that used by the examiners in their publications. Shortly, however, she realized she would not get the answer she needed by doing so and abandoned her solution. She forgot to cross it out, however, and now recognizes she should have done so. She thereafter began to accomplish a series of new calculations on the first page of the answer sheet but did not necessarily utilize that data for her solution to Part a. She admits she made an error in calculation for moisture on the second page. In that calculation, she used the study manual and admits now that she should have cited the figure she used.
As to Parts b and c, her use of some figures from Part a may have thrown her answer off somewhat. However, the 5 awarded her, indicating her solution was unrealistic, is, in her opinion unfair as she considers her answer to be quite realistic. The problem did not state what solution method to use and she feels her use of givens from recognized manuals such as the 150 pounds, should not be held against her. 94 pounds for a sack of cement used by the grader was also not given and her use of other accepted numbers should not, she contends, be held against her.
Petitioner believes a grade of 7 would more accurately describe the quality of her answer. A 7 means that the examinee obtained an appropriate solution but chose a less than optimum approach. The solution is, therefore, awkward but nonetheless resonable. Ms. Tignor believes that while her approach may have been awkward, she achieved reasonable solution demonstrated by the fact that it was only slightly off the correct figure. Therefore, she believes a grade of 6 would be appropriate.
This examination was an open book examination and Petitioner had her manuals with her. She could have easily determined the appropriate weights an "givens" from these manuals without choosing those she used. Ms. Tignor's conclusions that her results are realistic are contradicted by the Board's expert. Realistic results are, in engineering practice, not only the figure reached but also the method used in arriving at that figure. Here, though Petitioner's results are close, the approach utilized in arriving at her solution is unrealistic. Her approach showed an inadequate knowledge of weight/volume and calculations. Consequently it is found the grade is valid and was not arbitrarily assigned.
According to the Standard Scoring Plan Outline, each score from 10 through 6 has an indispensable criteria that all categories must be satisfied. Since Ms. Tignor's examination response did not satisfy all categories, the best she can be given is a 5 and that award appears to be justified by the evidence presented.
Question 421 was a four part drainage problem. Petitioner used as a part of her solution calculations based on a 100 year storm and this was determined by the examiners to be inappropriate. Ms. Tignor was awarded a grade
of 8 and contends she was not given appropriate credit. She relates that even Mr. Smith, the Executive Director of the Board of Professional Engineers, advised her she may not have been given full credit for her answer. She was given full credit for Part a but lost two points for part c which included a calculation error to which Petitioner admits. She contends however, it was so minor, only one point should have been deducted. Were Petitioner to receive an additional one point on this question, she would pass the examination which she failed by only one point. However, this issue must be resolved on the basis of lawfully admitted evidence and Mr. Smith's comment, being unsupported hearsay evidence, cannot itself sustain the rasing of the grade.
The Standard Scoring Plan Outline for this question reflects that to receive an 8, the examinee must demonstrate that all categories are satisfied, that errors are attributable to misread tables or calculating devices, and that errors would be corrected by routine checking. The results must be reasonable if not correct. For a 9, the examinee must demonstrate that all categories are satisfied; that a correct solution is arrived at but the examinee has been excessively conservative in the choice of working values; and that examinee's presentation is lacking in completeness or equations diagrams or orderly steps in solution, etc. Subqualifications for a 9 indicates that the answer is correct but that the organization of the solution is not logical. One error in calculation in any of the Parts from a to d, which does not affect the other parts of the solution, is acceptable.
Mr. Kenneth Weldon, the Assistant State Drainage Engineer for the Department of Transportation, an expert in the area of drainage to which this problem relates, reviewed the question and the Petitioner's answer thereto and would award a grade of 8 to her answer. He found various numerical mathematical errors which led to the wrong solution. In addition, Petitioner made various assumptions that, though supposedly supported, were, he felt, in error through her misinterpretation. In general, none of the actual solutions she arrived at were correct. Specifically, that portion of the problem to determine the cross sectional area of the waterway for establishing normal depth flow was done incorrectly. Because the Petitioner used incorrect equations throughout the problem, the depth flow computed is high. Petitioner did no analysis to determine whether or not any of the several situations relating to flow control were pertinent.
Mr. Weldon initially felt Petitioner's answer to the question merited a grade of 6. This means that the examinee knew all the proper steps but failed to interpret some of the criteria properly. He could not award her a grade of 9 which would indicate all categories were satisfied and the solution was correct, if conservative. Petitioner's solutions were incorrect. He subsequently changed his award to an 8, however, on the basis that the Petitioner's errors were attributable to a misread table or calculating device and would be corrected by routine checking. The result was reasonable, though not correct.
Mr. Weldon did not like this question even though he believed it appropriate for a one-hour exam. As written, it involves establishing and making judgements beyond what someone minimally competent would be expected to do. It requires materials that are beyond what are normally available to someone taking the exam. However, Petitioner failed to make proper provision to protect herself in a case where the question is inappropriate or incomplete. If she felt something was wrong with the question, she should have clearly stated the assumption she was making to solve the problem. This was her responsibility and she failed to do so.
In Mr. Weldon's opinion, Petitioner's answer might merit a grade slightly higher but not significantly higher. His reasoning is that Petitioner misinterpreted the criteria she stated for writing the problem. Her comment that the Department of Transportation uses 100 year storm criteria was incorrect even though that statement is made in outdated Department of Transportation publications. The basis for her answer is not well established or correct, or based on engineering calculations or judgement, and at best he could award no more than an 8.
CONCLUSIONS OF LAW
The Division of Administrative Hearings has jurisdiction over the parties and subject matter in this case. Section 120.57(1), Florida Statutes.
Chapter 471, Florida Statutes, regulates the practice of engineering services in the State of Florida and includes within the requirements for licensure, the passage of an examination, Section 417.015, Florida Statutes.
Petitioner contends that the grades awarded her on questions 124 and
421 of the Professional Engineer Examination given in April, 1987, were incorrect and should have been higher. Though her testimony can arguably be said to refute each of the criticisms made by the examination graders, there is an obvious difference of opinion between Petitioner and the graders as to the quality of her solutions. Absent a showing of error or arbitrariness and capriciousness on the part of the graders, their opinions should prevail. Petitioner here has presented insufficient evidence to show that the grades she received on the examination were in error or in any way arbitrary or capricious. To the contrary, both experts testifying on behalf of the Board of Professional Engineers clearly elucidated their reasons for determining that Petitioner's solutions were unprofessional and not well thought out. Neither would be willing to raise the grade awarded by the examiners and their opinions in these circumstances is controlling.
Petitioner has failed to carry her burden to show that an error was made in the determination of her grade, that the examination was improperly administered, or that her examination was graded differently than were the examinations of other persons. On the other hand, Respondent has shown that the examination is national in scope, being administered by the National Council Of Engineer Examiners; that it is graded by engineers according to a standard scoring plan outline provided by the National Council; and that the grade, assigned according to this prescribed outline was supported by the Petitioner's examination solutions.
Based on the foregoing Findings of Fact and Conclusions of Law, it is, therefore:
RECOMMENDED that a Final Order be entered affirming the score awarded to Petitioner on questions 124 and 421, respectively, of the Civil Engineering Examination administered to her in April, 1987.
RECOMMENDED this 10th day of June, 1988, at Tallahassee, Florida.
