The Types of Pre-Employment Tests

The Types of Pre-Employment TestsThe Types of Pre-Employment TestsIs it legal for employers to conduct pre-employment tests and background checks on job applicants? The short answer is yes. Companies can test applicants for employment. The longer answer is that the tests must be non-discriminatory and the tests must be properly administered and validated. If youre being considered for a job and have been asked to take some kind of test, you may be wondering what the test is for, how it will influence your chances of being hired, and perhaps whether its even legal. Here, to help put such requirements into perspective is a brief overview of pre-employment testing. Legality and Function of Pre-Employment Testing Employers often use tests and other selection procedures to screen applicants for hire. Some of these tests are closely focused on job-related skills and abilities, but others collect personal information for various purposes and are somewhat controversial. While legitimate concerns exist, pre-employment tests are legal, provided the company does not use the test results to discriminate on the basis of race, color, sex, national origin, religion, disability, or age (that is, to exclude applicants only because they are 40 years of age or older). Employment tests must be valid and must relate to the job for which youre applying. A major exception islie detector tests, which are illegal in most circumstances, both before and during employment, thanks to the Employee Polygraph Protection Act (EPPA). The type of testing discussed here is distinct from the testing required to earn professional certifications and licenses. The difference is that certifications and licenses are required by law or by industry standards, and are not part of the hiring process for individual employers. Types of Employment Tests Employment tests may look at who job candidates are, what they can do, or whether they can safely perform the physical tasks of the job. Ideally, thes e tests serve as tools for the hiring manager, and a way to avoid bias in hiring. Personality TestsPersonality tests assess the degree to which a person has certain traits or dispositions or predict the likelihood that a person will engage in certain conduct. Ideally, the objective is to determine if a candidate will be a good fit for the job and the company. Personality tests are usually written in such a way as to reveal any attempt at dishonesty. The goal of employment personality testing is to hire people who fit the profile of the ideal employee the organization is seeking. Talent Assessment TestsTalent assessments areutilized to help predict a new hires job performance and retainability. The focus is on potential skills and abilities, as distinct from either personality or developed skills revealed by an applicants work history. These types of tests help answer questions about whether the applicant will be successful if he or she is hired.Cognitive TestsCognitive tests are use d to measure a candidates reasoning, memory, perceptual speed and accuracy, and skills in arithmetic and reading comprehension, as well as knowledge of a particular function or job. Cognitive function is roughly what most people mean by intelligence, although true intelligence has many other aspects as well. Emotional Intelligence TestingEmotional intelligence (EI) is an individuals ability to understand his or her own emotions and the emotions of others. Strong emotional intelligence is important for most jobs and critical for some since emotionally niveauvoll people have the ability to work well with colleagues, interact with the public, and handle disappointments and frustrations in a mature and professional way.Pre-Employment Physical ExamsEmployers may require a pre-employment physical examination to determine the suitability of an individual for a physically demanding or potentially dangerous job. Pre-employment physicals are used to determine whether an applicant has the phys ical ability and stamina required to do the job. Physical Ability TestsIt measures the physical ability of an applicant to perform a particular task or the strength of specific muscle groups, as well as strength and stamina in general.Drug TestsThere are several types of drug tests that candidates for employment may be asked to take. The types of drug tests which show the presence of drugs or alcohol include urine drug tests, hair-drug or -alcohol testing, saliva drug screen, and sweat drug screen. It is important to note that while most alcohol tests determine whether the subject is currently intoxicated, nothing equivalent exists for any drugs. Drug tests determine whether the subject has used certain chemicals any time in recent weeks or months. English Proficiency TestsEnglish proficiency tests determine the candidates English fluency and are typically administered to candidates whose first language is not English.Sample Job Task TestsSample job task tests including performance tests, simulations, work samples, and realistic job previews, assess a candidates performance and aptitude for particular tasks. Think of these as something like an audition.Tests for Restaurant JobsRestaurants may test job applicants as part of the screening process to determine how much they know about the business, and how well they would be able to handle the job. Background Checks and leistungspunkt Checks Criminal background checks provide information on arrest and conviction history. Credit checks provide information on credit and financial history. Heres why, when and how employers check out job applicants.

Police Chief Job Outlook and Career Profile

Police Chief Job Outlook and Career ProfilePolice Chief Job Outlook and Career ProfileA versicherungsversicherungsversicherungsschein chief is a very visible leader in city government. The chief oversees the operations andbudget of the police department and is therefore praised for successes and held responsible for failures. The Selection Process Generally, when a police chief position becomes vacant, the city hires an executive search firm to complete at least some of the recruitment and screening tasks in the hiring process. Usually, the company advertises the position, looks for qualified candidates and encourages those individuals to apply. It may perform other tasks as outlined in its contract with the city. In the strong mayor form of government, the police chief reports to the mayor, so the mayor has the final decision on the selection of the new chief. In the council-manager form of government, the chief reports to the city manager. No matter who is the chiefs boss, the chief keeps that person informed on major issues and potential problems. Under both systems, a wise mayor or city manager will solicit input from other city staff and the community regarding the hire. The police chief is a high-profile position, and the public should be confident in the individual selected. Finalists may be interviewed by panels of citizens as part of the interview process. They may also be forced to attend public forums where individual citizens can ask them questions. The scene is much like a town hall meeting held by a politician. Education Police chiefs should have at least a bachelors degree, and many cities require or prefer a graduate degree. Many police officers have a bachelors degree in criminal justice. If an officer wants to one day become a chief, the officer should consider a master of public administration or master of business administration to round out his or her education in a way that aligns with the leadership and management duties of a poli ce chief position. Experience Individuals become police chiefs toward the middle and end of their careers. Chiefs have extensive, progressively responsible experience in law enforcement. That experience can include service in state and federal police forces. It must include service in a local police force like a sheriffs office or city police department. Police Chief Duties As the top manager in a police department, the chief has the final say on all hiring, firing and promotion decisions. Lower level managers provide recommendations on personnel decisions that must be approved by the police chief or a highly trusted designee. A police chief in a large department may have thousands of officers under his or her line of supervision, all of them putting their lives at risk protecting the community. New police chiefs are often surprised by the time demands the job places on them. City council meetings, volunteer meetings, luncheons, charity events, and emergency situations often happen outside regular business hours. Officer-involved shootings, major crimes, and other emergencies can pull a chief from bed at 300 a.m. to deal with superiors, subordinates and the media. Even though police departments usually fare better in the budget process than other city departments, managing a police department budget is difficult because of the many competing priorities. Departments must maintain a 24-hour a day presence on the streets, purchase expensive equipment like patrol cars and weapons, and fund prevention programs. Allocating funds for these and other competing priorities requires vision, strategy and excellent communication skills. The chief is the departments public face. Officers look to the chief for leadership, so the chief must be a good manager with high ethical standards. The community looks to the chief for answers on crime problems. In crisis situations, the police chief, city manager, mayor, and public information officer are in constant communicatio n ensuring that a consistent message is delivered to the public. Police chiefs may conduct press conferences and take questions from the media. These officials also make sure that only appropriate information is released. Examples include ensuring family members are notified before the name of a murder victim is released by the department and protecting case-related details that could tip off a criminal on how an investigation is going. Salary According to 2019 data, police chiefs typically earn between $101,149 and $113,622. Chiefs in very small department earn less than this range because the cities they serve do not have the financial capacity to pay more.

What to Do When Your Boss Lies

What to Do When Your Boss LiesWhat to Do When Your Boss LiesBosses can create plenty of problems. Sohonigweinimes theyre mean, sometimes they micromanage, and sometimes, they refuse to manage at all. But finding out your anfhrer lies takes a strained employee-manager relationship to anotzu sich level. Once that trust is eroded, it becomes hard to follow your boss direction, wondering if he or she is taking you down the right path or leading you astray. Everything that comes out of his or her mouth becomes questionable- information about the companys status, promises of raises or new projects, and even affirmation for your good work suddenly seems questionable. And that makes it extremely difficult to do your job effectively. So what happens when you catch your boss in a lie- or several?For me, having a manager who lied wasnt so much an issue of figuring out how to make him or her stop. Lying usually isnt something you can simply manage out of someone. And so, it became more about rec onciling with myself if I could continue working for a boss I didnt fully trust. To do that, I asked myself a couple key questions that helped me get down to the root of the issue and decide how I should move forward. 1. Where Are His or Her Intentions?A couple years ago, my entire department was working on an extensive, time-sensitive project- which involved contacting our entire customer kusine one by one. I was one of the department supervisors, so the other managers and I regularly met with my boss to discuss the teams progress. To make sure we met our deadline, the boss decided to announce that the companys executive team had given us a deadline of four weeks- when it was actually six. He figured that by fudging the number just a little, he could ensure we met the executives timeline- or even beat it.In the end, we were able to deliver the completed project to the companys executive team ahead of schedule- which certainly put the entire department in a good light. In another jo b, I had a boss (the owner of the small startup) who would often stretch the truth- especially to the media. Whenever she was quoted in a newspaper article or interview, shed overestimate the number of our employees. Shed boast about employing over 350 staff members- when I knew that we only had about 100. The difference between the two? The first boss wanted the team to succeed to deliver good results ahead of time that would boost the departments reputation and value within the entire company. While I wont condone the lying behavior, from what I could tell, he had good intentions.The second manager wanted her company to appear successful. She wanted the credit and recognition for running such a large company without actually working for those impressive numbers. Lying created a direct shortcut for her to achieve that goal- and proved her selfish intentions. 2. How Does it Impact You and Those Around You?In the first situation, Ill admit it- the tight deadline certainly added some stress and pressure to the teams daily lives. But considering it didnt require hours of overtime or employees staying late into the night, it proved that it was something the team was capable of all along- they just needed that push. In short, the feigned deadline made the team work harder toward success. The other situation, however, put everyone in the company in an uncomfortable situation. If we were asked questions by any of our clients or media contacts, we had to decide whether to back up our boss and perpetuate the dishonesty or speak up with the truth and risk our jobs. The impact of the two situations varied greatly. While one pushed the employees to greatness, the other forced the employees to dishonesty. In the end, no matter how great your boss intentions, or how little the lies impact your work, the truth is that discovering that your manager has lied even once is enough to chip away your trust in him or her. And so, you have to evaluate your relationship to determine i f that is something you can work around- or if youd rather find a trustworthy boss elsewhere. These questions provided me with enough clarity to realize that I could still work with the boss in the first situation. I saw that his intentions were good, the impact was beneficial, and overall, I still respected him as a manager and leader. The dishonesty in the second situation, however, was something I couldnt overlook. This boss continually lied for her own benefit- and her benefit only- regardless of how it impacted the rest of the team. That, in itself, immediately changed the way I viewed her and took away from the respect I once had for her. I didnt want to invest my time and effort in working for a leader I couldnt trust or respect. Catching your boss in a lie- or several- can be a tricky situation. But ask yourself a couple key questions, trust your gut feeling, and decide whats best for your career going forward.Photo of lying boss courtesy of Shutterstock.

Introducing the Worlds Most Powerful Tidal Turbine

Introducing the Worlds Most Powerful Tidal Turbine Introducing the Worlds Most Powerful Tidal Turbine Introducing the Worlds Most Powerful Tidal TurbineThe oceans a massive thing. And with that other massive thing, the moon, it creates tides of massive power. If you want a piece of it, you need a massive turbine.The folks at SIMEC Atlantis Energy have created just that. Their AR2000 will be the largest single rotor tidal turbine that the seas have ever turned.At 2-megawatt, AR2000 will be the worlds largest and most powerful single rotor tidal turbine. Image SIMEC Atlantis EnergyIt is bedrngnis, however, the largest in size, but in powerit has a maximum output of 2 MW. In fact, its the same size as its predecessor, the AR1500, a 1.5-MW turbine. But getting the same power out the same size required some serious engineering ingenuity.The approach with this turbine was based on asking ourselves the following question how do we get more out of what weve currently got, said Nigel Hopley, the companys mechanical engineering manager. How much spare capacity is there in the existing konzept, and then how could we change the control philosophy to increase its power and its annual yield?For You Bacteria-Powered Solar Cells Are Ideal for Cloudy ClimatesThankfully, the AR1500 proved to be plenty rugged.There was nothing spared, Hopley said. It was, If in doubt, put in a little more provision than you need to because the cost of failure was far greater than the cost of being slightly too expensive.With the AR1500 at work in the water, the company found that load spikes and fluctuations were not as great as they had predicted. In essence, theyd over designed for rougher waters. That gave us some extra capacity, Hopley said.To ramp all the way to two megawatts, the engineers had to change the way they approached harvesting energy from the tide.Typically, tidal turbines are designed to run in high sea states at full power until a wave height threshold is reached. Then they shu t down. Sticking with such a design philosophy would have meant having to scale up components to create a 2-MW machine. Instead, in situations with high waves and flows the turbine reduces its power setting, which also reduces the loading. These powerful sea states are rareoccurring roughly two or three times a yearso for 98 percent of its life the AR2000 will be set to operate at 2 MW. This small concession allowed SIMEC Atlantis to avoid a larger, more overhauled design.Its an overriding principle to get the most out of what we have rather than scaling up, Hopley said.Another major advancement is the ability to hook up multiple turbines and send the electricity they produce back to land through a single cable.Others have had individual cables for each turbine, and that is something that changes the turbine a little bit, but has an enormous impact on infrastructure costs, he said.Tidal turbines maximize their output by being able to turn with the tides. A tide doesnt always go out at the same angle that it comes in, so turbines turn to face the full force of the flow. To operate at 2 MW, the AR2000 couldnt stick with conventional brakes without increasing its size. So they used a new coupling which reacts to torque uniformly, reducing stress and keeping the design compact.Several AR2000 turbines are likely to join SIMEC Atlantiss Meygen array (the largest array of tidal turbines in the world) off the north coast of Scotland.We are working to have it deployed somewhere around the middle 2020, Hopley said. But we dont have the order yet.Subsequently the AR2000 may crop up all over the world. The addressable tidal market is a moving feast, he says. The more we look, the more we find. It may not be as big as wind, but its still huge, absolutely massive.Michael Abrams is an independent writerRead More Breakthrough Makes Graphene Easier to 3D Print Battery Capacity Gets a Boost Industry Tackles Challenges in Mass-Producing Flexible Solar Panels For Further Discussi on The addressable tidal market is a moving feast.
